Who thinks this is fake outside horribly HORRIBLY stupid people? They clearly did the demos up on the stage, and they worked just the way they were supposed to, minus the hiccup with cujo's avatar being funky. Even that proves they were doing it real time, you don't put a mistake into your presentations just for shits and giggles. Even the PETER MOLYNEUX project was on display for real people to use later in the show, and while it didn't have an enormous vocabulary, it did everything else it was supposed to admirably. IGN called it very impressive.
So how would this be fake in the least?
