Meh. Count me among the naive peeps to whom Cormacaroni refers. I'll admit to being stunned at the hubris ACTI has displayed in this last couple of years, starting around the time they voltron'd with Blizzard. Grabbing Red Octane just to get the Guitar Hero brand, then running it into the ground across every platform, well, that was predictable. The moves they put on Scratch! to protect DJ Hero were low, and even cunning. But whatever is going on here with IW is likely deeper than anything we've seen.
As a studio of Activision, their ability to move is likely very limited. When IW chose to be acquired by Activision, their options for changing their professional direction became very limited. If they met with other companies while considering those options, they may be compromised. Activision is likely watching them as closely as any man who has acquired his woman through infidelity; after all, there is precedent.
