I just came here to correct some false info about the engine.
Except you were here before that? Even so, you quote Swen saying it's a different engine built on technology they already have. I could link an article claiming that it's the same engine. You can add or change a few things and call it a new engine, when really it's just an upgraded engine... but that's really all just semantics.
Regardless, my point still stands. They're not building a completely new engine from the ground up - they're using parts of what they already have. I don't see them taking the game in a drastically different direction... but I suppose we'll see.
