"Confirmed" Issues:
- Forced online activation for all games
- Massive emphasis on TV, services and non game related focus
- Live TV services available in US only at launch, requires separate device
- No self publishing for indie devs
- No headset included
- Over emphasis on Kinect interface
- Xbox One not being backwards compatible with the 360 games or accessories.
- Microsoft's failed attempts to correct PR with contradicting FAQ's, vague responses, misinformation.
Hardware:
- DDR3 confirmed instead of GDDR5
- Potentially Only 5GB of the 8GB ram available for games
- Only HDMI for output.
- 3 OS's? At best, confusing, at worst, a nightmare.
- Kinect needed to be plugged in for Xbox One to function
- Non-replaceable Hard Drive (though not as much an issue, as external drives are supported similar to other consoles. could be a repair issue, though)
- Console uses a large external power brick (Conflirmed by DF/Wired)
- Console is not designed to be placed on its side
Problems with the announcement itself:
- EA games prerendered using in game assets
- COD looked less than stellar
- Quantum break reveal was confusing
Unconfirmed issues that still need clarification:
- How much is this gonna cost?
- Complex used games system that is anti consumer?
- How the hell does game borrowing work?
- Charged fee for playing used games on non linked profile?
- Console that needs to be connected to internet every 24 hrs to play games? (Phil Harrison says one thing, ms backtracked a bit later)
