A new engine, based largely on an old engine with a few face lifts. Sigh. The WiiU, or whatever they settle on, is a console that's 2+ years behind computers on the day it is released. Any engine based on that old of hardware is going to be either knee capped, or run like a dog. The only real way they ever "improve" is to keep the functional structure of an engine, but improve graphical performance. UT99->UT2003->UT3 all play the same, despite being a decade apart. That kind of a lack of evolution is kind of sad.
