do any of you know whether if you have 2 ps3s, get host on one, invite the other one in, and back out on the first, if the second one will stay host? basically what i am asking is if it works like cod 5 where it only has to migrate once before the game starts, or is it a new system where no matter how many times it migrates before in the lobby from people leaving, etc. it will always migrate one last time before the game starts?
