Cheaper to pay a bunch of ex-Bizarre employees than to buy the company itself. No surprise, there. As soon as Activision stated they were going to close it, it was going to close. Other companies'll just wait it out and poach the talent without having to deal with the backlog of issues in the company itself.
Next thing you'll know, we'll hear word how a bunch of ex-Bizarre employees are forming their own developer and how they're working on a racer. If they had a sense of humor, they'd call themselves, "Absolutely Normal, Inc." Because that'd just be bizarre.
