I really can't wait to watch all of this unfold. It will be interesting to see what the market dictates. Most seem to assume Sony should be worried (and they should be concerned) but what about MS if they do decide to pull CoD from Sony's platforms? Gamers can be very fickle and what franchise has been the best of a genre can quickly change course. If MS pulls CoD from Sony's platform will more people switch consoles? Or will more of those people switch what FPS they pay? I believe most agree that Sony has the majority of CoD players.
I'm not saying CoD will vanish. I am saying the dominance could end if there is a sudden change in platform availability.
You have to remember that the360 had the majority of COD players back in the day. Gamers just want to play the games and will go where they are
