It'll be complete by the time it gets ported. Try reading up on this before you talk out of your ass.
I'm still skeptical on this. On one hand, it'll be nice to play because I could play it without such a low FPS, but on the other hand, will it supports texture packs, mods, etc.? It's apparently going to be for XBLA, so who knows. I know XBLA games have more "freedom" than retail games, but yeah. We'll just have to wait until winter to see.
