Ok at last i figured it out. Just got done playing for the last 4 hrs, I can defiantly force host on ps3 with a lagswitch. now I'm trying to figure out how to recognize if you can keep host after a game has finished and when the scores reset to zero. But that in itself dosent seem to be nothing more than a nussience, since with the current format/system in place it seems to only migrate host after about six games or so, and it's very easy to start a new game as host all over again.
Now just so you all are aware a lagswitch in mw3 dosent work like cod4, waw, blops. It works like it did in mw2. You can't I repeat can't just hit the switch take a head shot and move on, it's also very hard to stop bullets from killing you. If you just hit the switch and shoot you won't even get a hit marker, and when you release it you will be dead. But this is sort of a good thing as if you pulse the switch off n on very fast as you shoot in bursts say quick successions of 2-3 bullets, and move in a left or right continuos motion then it's money n the bank. You may find yourself asking why in the he'll is this sort of a good thing. Well because I've watched/analyzed games from the theater mode and it will only look as if its a very lagy game and it will not be easy to tell if you were cheating. I've watched from lots of perspectives of the other team and if done right nobody will know the wiser.
