The WiiU should have the ability to handle the new Unreal Engine. MS nextbox is going to handle it considering PC devs are going to utilize it, Japanese devs will probably make engines that come close to the new unreal engine or try to make a better one and sony and his team of devs will probably try to make a better Engine that needs a slightly more powerfull console...
If WiiU can't handle it I give it 60% chance that most devs in a few years when the nextbox releases will not bother with the WiiU.
