Yep, and for example, we will never see mario on an open platform,
wanna play mario or zelda? You have to buy nintendo hardware.
So lot´s of IP and some studios are bound to hardware.
The solo existance of an open hardware will never be enough to dismount this.
What could be good, is for homebrew or small growing indie studios as it offers another market to help push things.
But heck, android? I hope they accept native code direct to their hardware.
Either way, if things go ok, we GLB users are in to gain I guess.
GLB currently support both native and android.
March 2013 is a long road...
Yeah, now that you mention it, Android really needs some new, imagination-catching, fun IP of their own. Some amazing game that's only on Android. Would be interesting to see what Apple responds with if that somehow happened (unlikely, but hey it's nice to dream).

I think the way to approach the Ouya is with a keen-eyed watchful interest and a healthy dose of skepticism. ie. keep an eye on its development but don't get your hopes up.
