I also believe (correct me if I'm wrong) that this device isn't going to be using 'traditional' android apps, and will have more of a 'gaming' focus.
I also read that all games must have a 'free' mode of some sort (either trial, free with in game purchases, or totally free)... and I also read that it will allow for a very wide development base (anyone who owns a OUYA will be able to develop for it), so I'm expecting a lot of more 'indie' or 'home brew' games as it were. Hell, we might even be getting some open source games...
I like to think a few GPL games will come out due to this... maybe like the linux gaming community.
Wikipedia also said that a N64 emulator will be available... imagine getting to play golden eye split screen again!!
