My prediction on the bodies staying: This is just setup for a bigger shock on a later floor, where the dead bodies don't stay dead. No idea on if they will be zombies, vampires, or something new.
Also: I'm kinda wondering if Kayaba is approaching the point where he goes "ok, this is not as planned at all, I'm pulling the plug" and Cardinal says "I can't do that Dave."
