Also something I hadn't mentioned in this thread is that, despite mainly being interested in the guitar bits, I bought some other stuff a couple of months ago; HMV were having a "2 for £30" deal on selected goods and they had a few instruments in there, so I picked up a microphone and a "Portable Drum Kit". Coupled with my
GH2 and
GH3 guitars, I technically have a full band now

but the guitar is still my favourite. Unfortunately I'm a bit out of practice lately having been distracted by other games, but it's still great fun.
(oh, and whisper it, but there were once
comments floating around about
RB3 as a 2010 release. To my knowledge, the only foundations for the rumours are that Alex of Harmonix said that RB would break it's annual release cycle and so there wouldn't be a sequel released in 2009. I'm doubtful about the
RB3 comments myself, as there's nothing stopping them saying that there won't be a sequel released this year, but hey...)
