I disagree. I don't think casual gaming, like what is found on iOS, will ever take over or replace traditional, hardcore gaming that you see on high quality PCs and consoles. I think they are separate markets that can exist together just fine. The Ouya would be hard to improve upon imo, but I don't see it taking a huge market share away from other consoles.
Yes but children will grow up with iOS games, so if you and me are too old to play or if we outgrow(?) our gaming phase there will be noone to take up our place. And if you are like me then you would rather play a medicore iOS game than no game at all.
And gaming companies see that this market will die out in the future and less games are being made.
