Guitar Hero World Tour peripheral from Neversoft's Brian Bright who "wouldn't go into detail about what it will be," though he apparently said the new peripheral was "specifically for the game's Studio mode."
We've reached out to Activision for some kind of comment or confirmation; however, until then, speculation seems to be the name of the game. G4 is guessing keyboard, which is all well and good. And who knows, it may well be a keyboard. We're not oracles here. But as long as we're just guessing, why not guess a little bigger, y'know? That's why we're happy to announce Joystiq's official guess for the rumored new Guitar Hero World Tour peripherpal: keytar.
