The big problem problem that new consoles are fighting for is: a reason to exist. Most games demo-ed so far look possible on the current generation of hardware. Crowd sources AI is an interesting twist, but possible on current consoles. Killer Instinct is an odd thing to revive, but it would play just as well on a PS3.
Suddenly Microsoft comes out with a console that:
1. Phones home every day.
2. Bans game lending.
3. Possibly cripples the used game market, or maybe not, nobody is really sure.
4. Requires Kinect to be always on, because that wasn't a disaapointment.
Their sales pitch of "You can play games that are basically last-gen games, but with fewer rights" has had shocking trouble resonating with consumers.
5. Integrates with PRISM natively, giving Big Gov (which is quite corrupt these days) a chance to look right into your living room.
7. Profit at the expense of your privacy.
Microsoft was the first big tech company to roll over for the NSA (that there's pretty good knowledge of NSA backdoors into Windows for years just shows their further corrupt nature). They give NSA exploit information prior to patching it.
There is no way I am going to give Microsoft (and the government by proxy) a device that can tell when I entered a room, when I leave, and what I'm holding for f*cks sake. Just for some games?
To those who think that Ouya and XBone/PS4 aren't comparable - I'll tell you something - when several of the options is anathema, the remainder, no matter how poor, are all I'm willing to commit to - that it costs so much less is a bonus. I still haven't figured out the Wii U, and I'm not sure I have time to.
Fun should be simple - I debug/analyze and get systems working at my day job - I don't need to mess with all that @ home.
