According to Epic Games, Unreal Engine 4 will be packed with the same features and tools for all devices from low end to high end. Moreover, the company stated that every platform from the Iphone to high end PCs will be supported by Epic’s next generation engine."

This was to be expected, it's the same as UE3

Which helps explain the "Wii U support" rumor.

They'll find some way to not include Nintendo in that range.

Water, meet fish! Water, meet fish!!

I will laugh if it's compatible with iphone but not with wiiu.

So what if WiiU wont support it, UE3 on wiiU will stil look 100x better than UE4 on iphone.

Good 'ol Epic, managing to support the iPhone but, somehow, not the WiiU.

Cool, I can't wait to play Unreal Tournament on a touch-screen!

all right

Indeed, so the next Iphone is more powerfull than the Wii U =D.
