Sorry if this is off the current topic of the thread, but I keep thinking about the detachable controller(s) aspect of the leak, and I just can't see how they could make that work. This is assuming it is like most of the concept drawings, which have two parts of the controller that come off the side. If you think about doing that on a 5 inch screen... The 2 sides would just be way too small, imo, to make it comfortable. Current 3DS size controls are only passible due to the fact that you are holding it with both hands. Separate those sides, and there just wouldn't be enough there to grip onto. Aside from that, there is also an issue of the detachable controls in that configuration being sturdy enough.
So, what configuration might work better for this concept? I started thinking of something similar to say, an Asus Transformer. This would mean that it's a clamshell design, with the top half being a whole screen that detaches, and the bottom half being a controller.
Now, doesn't this concept sound familiar? Where have I seen this before... OH, THAT'S RIGHT:
It's Falco's gaming device from the Star Fox anime. Now, in that picture, also notice how the two parts fold out of the bottom in order to extend the grip area. That design in the photo isn't very well proportioned, but it is just an anime short, after all. I think you could adjust it so that, when the extended grips fold out, it would be a lot more similar to something like a Wii U Pro controller, albeit much more flat. This would work well as a regular console controller for when the screen portion is docked.
One other thing, for reference, this would also be very similar to the Nvidia Shield Portable, but with a detachable touch screen and a form factor that's a bit tighter.
Anyways, what do you think? Does this configuration seem a bit more feasible for what the leak was suggesting?
