Alright... well my estimated delivery is not for another 2 weeks... I'll definitely post up my impressions once I get it in.
I'm mostly interested in it to replace my old modded Xbox running Xbox Media Center... since it can't stream HD video, it uses component instead of HDMI and has wired controllers... Theoretically the OUYA can do all of those things, any good games that come out for it will just be icing on the cake.
For those of you interested in what games are out on it here is a list of them by poularity:

I agree Polarity does sound good, I'll be sure to check that out.
I'm also curious if we'll be getting other Moble only games. I was pissed that Deus Ex: The Fall was going to be iOS and Android exclusive, but I'd be ok if I can play it on Ouya.
