They're cutting down to just Guitar Hero and DJ Hero now.
Funny enough, Harmonix is now the music rhythm game whore as they've been trying to see if there's interesting for more band specific games.
I feel like I'm almost done with the genre now. I appreciate that I can play 99% of the songs I've bought from Rock Band games in Rock Band 2, but I don't really need the entire Green Day catalog on disc. I bit the bullet with The Beatles and I almost feel bad for supporting such a bad concept.
