Aha, it’s all becoming clearer now. Activision’s oddly desperate-looking promotion to give away Guitar Hero: Van Halen to anyone who bought Guitar Hero 5 in September is starting to look a little more nuanced than it first appeared. 5Frets reports that copies of Van Halen are showing up in players’ mailboxes already — nearly three months before the game is due to arrive in stores.
Given that actually signing up for a copy required a fairly complicated process with what I expect was a fairly low participation rate (think mail-in rebate), this is looking more like a daring marketing drive and less like “We need to get these discs out of our warehouses no matter the cost.”

this game is super fun!
Yep I got mine today in the mail! Yay!
Basically a reskinned GH:M, but hey, that was a decent game. And it was free! FREE!
