Any idea if Guitar Hero : Greatest Hits will be sold with new band kits or it's just a standalone game (i.e. no new guitars, drums)?

Was thinking of picking up a drum set this weekend, but I'll hold on if there's a new drum kit coming out (which hopefully fixes some of the current issues they're having).

Btw, GHWT's March DLC will have Queen's "Weeeeee r da champions".
