1- Nintendo has been moving away from the sensor bar for some time now. Most motion + games don't use it, and the Gamepad doesn't need it for its motion sensing. My upgraded remote includes a magnetometer to use absolute compass points as the fixed position to check for drift.
2- There are numerous wireless HDMI products on the market that don't need external power for the recievers. HDMI is a two-way seystem, capable of streaming data and power back to low-draw devices.
Camera control was a major flaw with the original Wii remote. That's mainly what the circle pad is there for.
I don't know about the magnometer, but motion + needs to be calibrated before each use, so it's not ideal for a Roku/Apple TV type box for casuals. I understand the convenience you like conveyed with the dongle, but there are other problems as well. I just think a little box could be done really cheaply like Chittachong has said and would provide more options for both Nintendo and consumers.
- A console with a shared library would give you better IQ than a dongle.
- A console could hold more content and have server like features
-- Imagine moving a game from the console to an SD card and then putting it in your handheld.
- A console would allow for split screen multiplayer while simultaneously transmitting handheld devices.
- A console would allow you to target the console market.
- A console, if wanted could be more powerful than the handheld and offer exclusive games.
-- If a game was tailor made for the Wii remote or a different hardware attachment, it would be easier cheaper with a console.
- A console could theoretically provide better graphics and/or exclusive games/content while still being able to play all the handheld games.
- The handheld could have exclusive games/content (like touchscreen/camera use) while also having the added benefit of being synced with your console (exactly like the Wii U & Gamepad) to control the OS/games.
My idea of a hybrid is basically targeting two different audiences with the same games, but the goal is to get people to buy both systems. There would still be a reason to buy each one depending on your preferences. 99% of the games would work on both systems, but in some cases one of them would have additional features/content or possibly even made from the ground up for that system. Basically, Nintendo would make it to where if you bought their handheld, you would eventually want to buy the console too for the additional content and vice versa.
that, plus
- move away from PowerPC to an ARM based architecture, as long as PowerPC runs their consoles there will never be a portable Wii U
- move away from multi-GB optical disc AAA to simpler games that can be downloaded even on lower connections
this exactly. I would love me some Game & Wario, New Super Luigi U and Wii Sports, and none of them require a big console and a tabletish thing
hell even Luigi's Mansion 2, Zelda LTTP 2 and Kid Icarus Uprising at home TV would be awesome and no need for a big console
I think moving away from PPC and going to ARM is a given. Sony considered ARM for PS4, but opted for X86 due to porting convenience. The power is there with ARM, we are simply playing a waiting game. I think Nintendo is the most likely one to use it in a console in the future. 3DS is capable of delivering console like games already, the problem is that the games are stuck on that system. As you said, there are a plethora of 3DS games that would be nice to play on the TV. Right now the Wii U has all the controls needed to play 3DS games with the Gamepad. That's why I think Nintendo should start making most future games for both systems and make the 3DS and Wii U the end of an era and start preparing people for this hybrid future.
Currently, this will require coding the game for two different architectures, but in the future, the handheld and console could share the same architecture. By starting to port 3DS games to Wii U now, they will be preparing people for the future. Moving to a new architecture unfortunately means losing all backwards compatibility, but at least they will have a set standard going forward to build off of.
To minimize cost and enhance compatibility, I think they should drop the dual screen on the handheld and include a traditional controller with the console. The controller may need a touchpad (like the PS4 DS4) built into it though. Some games (like Kid Icarus) could have two different control schemes. One would be for the handheld (touchscreen) and one for the console (Wii remote and nun-chuck). In the options menu, you could select your controller preference.
I don't know about DS & 3DS, but GC & Wii games are rendered at a higher resolution internally and then displayed at a lower resolution on the TV. A similar approach could be taken going forward. All games could be displayed at a higher resolution on the console than the handheld and the clocks and specs could be adjusted for it. Like the GC & Wii, the handheld games would be internally rendered at a higher resolution than its display would allow, but the console will unlock it. The other option is to have the exact same specs in both devices, but it would make the handheld more expensive (hi-res screen) and would also lower battery life.
The console could also have the benefit of split screen multiplayer while also streaming data to handhelds just like DS & 3DS does it. This could allow for a lot more people to play together locally than is currently available. Perhaps a special chip or line of code will need to be detected for this function to be enabled, but when you see the option for split screen on the handheld, it would simply be grayed out and not selectable. As I said, the goal for Nintendo should be to get people to buy both systems and this would be another reason why. The Wii U is limited by only being able to stream to one gamepad and the price and availability of a replacement is also a factor. This would be a way around that.
There's a way to do it going forward and there's a way to transition it starting now. The big question is what Nintendo will do. We can speculate all day long about this, but there's no telling what direction they will take.
