While UE4's engine's trailer looks amazing on its own, it doesn't seem all that hard to pull off lighting effects now. I also think UE3's graphics really were the big leap this passing gen. They were the defining moment this gen and if Wii U can pull off souped up UE3 graphics and still run a game that uses UE4 it's already at an advantage than the precursor systems. I stand by what I have been saying before, everyone is hyping up Sony and Microsoft's next consoles as being huge behemoths that are gonna blow away the PS3, Xbox 360, and the Wii U and make them seem obsolete. However both MS and Sony are in massive debt and a new console from each that uses highly new tech is gonna cost some serious $$ again. The consoles are gonna be comparable and equal to the Wii U in graphics processors and power, if only a slightly bit more powerful (look at Ps2 compared to Xbox, and GC, both of whom came out a whole year later). It's gonna be like the GC, PS2, Xbox era all over again. All it is gonna come down to is who's online, communication, partying, casual, hardcore, etc. infrastructure is going to be the best. Lastly whoever the 3rd Party publishers cling/develop for the most is who'll get the most games this gen.
