and Ouya doesn't count(because it is an open platform).
And because Ouya will be niche at most. I don't see EA wanting to launch its own console, especially with the costs involved and the millions they would lose in sales from not having their games on other systems. Origin is not a console, just a delivery method (like iTunes, Amazon, eMusic, etc.).
I wouldn't want game cases to be as small as PS3, Sony did that just to be different. People like standard size cases for a reason, they look better and fit neatly together. Whether its a DVD, Xbox 360 game, Wii game, etc.
