If you feel like you haven't got enough Hero games to look forward to, you'll be pleased to know that Activision are bringing Guitar Hero to the PSP

An Activision investor call made mention of a PSP iteration of the rhythm game, which promises to feature "a drum component," according to Gamespot.

There are no other details to speak of at the moment, but you can bet your top hat it'll show up at Sony's E3 conference tomorrow.
