From weblogs.variety.com:

Skateboard Activision is a publisher that knows, and has come to love, peripherals. After all, they’ve helped drive the "Guitar Hero" franchise to well over $1 billion in revenue. (Unlike MTV, Activision typically makes money on its music hardware, though it did have some hiccups with "World Tour" drums over the holidays.)

Which is why it makes some sense it’s going that route with the next "Tony Hawk" skateboarding game, coming this fall. Rumors that the as-yet-untitled game would use some kind of peripheral started last summer. But two sources who have seen the game first hand have confirmed that it will indeed eschew controllers and rely on a board-like peripheral. I’m told it won’t be about precise balance (if you want to do that, just get a real skateboard). Instead it’ll be about grabbing and manipulating the board to pull of all the tricks for which "Tony Hawk" games are known. Because the peripheral does a lot more than just measure where players are standing, I’m told it’ll be available for the Wii version as well — it won’t just rely on the board that came with "Wii Fit," as EA’s "Skate It" did.
