Really have to laugh at some of delusion happening in this thread.
To the people stating with confidence that "it will have to be available for Wii-U too" - Why? There have been reports that the Wii-U doesn't match the 360 and PS3 in some respects, why is so outrageous to think it won't run UE4? Of course, it may scale, but aren't we looking at a similar situation to what we have now with the Wii, 360 and PS3 (ie. scaled back ports for Wii). Nobody has any investment in the Wii-U at this point from a consumer perspective, so I don't get this kind of blind faith people have in Nintendo's next system.
I also can't believe some people are saying that Epic are overestimating the power of the next generation of consoles. - Do you really think they haven't been talking to Sony, Microsoft and Apple? They'd be crazy to release an engine that isn't primarily aimed at the next generation of consoles.
