True, but with Rock Band Blitz, they didn't have to make any new instruments or what not, and again, if they made another Track Pack that was worth buying, it could also throw them back into the huge game. And there's still tons and tons of RB fans out there, a lot left because of what RB3 had to offer - real instruments. It wasn't until about two months ago that I got the wire to hook up my keyboard to the game, and I love it, but I'm left handed, and the guitars that they released for the game are NOT left handed guitars at all. Still, I love the game, and would love a new Rock Band, if not for a new experience, at least for another killer setlist.But let's face facts. Rock Band 3 didn't sell anywhere near what was hoped it would. The fan base has dwindled to probably less than 20,000 at this point. It costs a LOT to manufacture the plastic instruments, and retailers have been burned once by the big kits cluttering up their stores when the bottom fell out of the genre. So getting them to stock the big band kits again is going to be a huge hurdle to overcome.
