probably will move more ps3s than x360s. many people who havent bought a next gen console would probably associate gta4 with the playstation brand as it has been available on the playstation in the past. not that the x360 wont have a boost.
but brand recognition helps a lot. for example, here where i live, if you want a soda, people say coke even if their buying a pepsi. people say colgate when buying toothpaste even if their buying another brand.
