Bobby Kotick is all about the bottom line and he's made no bones about it. The Activision CEO has continually called for a PS3 price cut (which one would assume isn't because of a sense of altruism on Kotick's part), and since Sony isn't budging on that issue, he's starting to throw the full weight of Activision around.

You can read all about the back-and-forth between Activision and Sony as well as all the other big PS3 news this week in this edition of the PS3 Weekend Warrior.
