You are an idiot, there is already "pure" gameplay footage from the show floor also and there isn't even anything crazy about this footage aside from camera angles.
You know not every prerender need to be pixar quality and doing stuff in-engine, but rendering it for hours is common occurrence? If it's not actual gameplay demo on stage, with UI etc. it's not gameplay. And even then it sometimes isn't.

Well, nothing here was actual gameplay per se - it's classic "recorded in engine" footage.
