What Console are you looking for and maybe getting?
The PS4 and 720 are just being upgrades to the current PS3 and 360 (Hopefully big upgrades). One drawback is that there are rumours that there will be NO backward compatibility so if you still want to play your 360 and PS3 games then you have to keep the old console
The Wii U has already been released but will probably fall behind in graphic capabilities since I've heard its the same as the PS3 and 360
The Ouya is interesting it uses Android I heard it uses the service called OnLive to get its games. It streams the games instead of downloading them too. It is said that it will have Ouya exclusives too. For more info go to
www.ouya.tv for the console and
www.onlive.com for games and stuff. Oh yeah it also costs only $100
The Steam Box which is my favorite! I'll probably get this over the PS4 depending on prices. The console itself runs on Linux and could be upgraded to Windows. The Xi3 Piston is based off of X7A which is a new series coming out later this year. Xi3 has been making the X5A for 18 months now. Anyways the Piston is the only announced Steam Box so far and the price has not been announced yet. I'm excited for the Steam Box it will be awesome!
The last one are Android Consoles theres not a lot to say about them just they basically port apps on google play to a console
