No conspiracy. This guy has said nothing new, his source has said nothing new, but if he wanted to talk more about this so-called "conspiracy" he would have done better to talk about when Activision was threatening to drop the PS3 platform.
When the PS3 is the lead platform or a game is being developed on both systems at the same time, they tend to run the same or the PS3 tends to have an edge. When the 360 is the lead platform, and they port the game, it tends to be a shitty running game.
