I just came across this article http://www.vgchartz.com/article/252932/unreal-engine-4-support-for-ouya-now-available/

Anyone remembers the following quote: 

When someone asks if Unreal Engine 4 will work on Wii U, Epic co-founder Mark Rein bursts out laughing. "No," he says.

But why am I comparing? OUYA's success is impossible to ignore. 

Ouya Master Race.

What will unreal 4 engine bring? better graphics capabilities or something?

Not shocked personally. Still, it's worth noting.

You compare the weak, unimportant and terrible Wii U with the almighty successful Ouya!? What has gotten into you?! Tss! You obviously lost your mind.

EDIT: That was sarcasm. There are always one or two people who don't get it...

UE4 gives as much support to the Wii U as the general public does: zero. This is a 2 horses race since Nov 2013.

This is almost laughable. Oh, gaming industry, you're still as shitty as always.

And the WiiU will probably continue waiting for another while!

UE4 on PS4/XB1/PC =/= UE4 on Ouya/Mobile

Just the engine. Unity is probably a better fit for the Ouya.
