Dead or Alive 4... for the XB360?

That's a bit of a misunderstanding. The engines for various 3D computer games, mostly FPS games, but some adventure games too, did in fact use the same original game's engine, but not all, not by a long shot. And no, I don't mean the ones that looked aweful. I mean the ones that actually looked just as good but used a unique engine, simply so they had control over it. Nintendo won't be using the new unreal engine for sure, though games will likely look just as good as it, or better.
