Actually, I pre-ordered my copy back in August and it was the only copy to arrive at my EB. It's really hard to find, no other store I went to around here had any. I think more copies will be in by the 28th or the 3rd of January from what I've gathered.
And YES, it's very fun. Since I've always sucked at Guitar Hero, the difference in difficulty doesn't affect me at all. Singing is really hard (even on easy) for me. The drums are surprisingly close to the real thing (on expert), even down to the bass notes. It's harder to do rolls and if you hit a bass note when one isn't there you get penalized (hence my annoyance with Mississippi Queen), but it's still a lot of fun.
I got a few DLC songs, Buddy Holly by Weezer, the Queens Of The Stone Age and David Bowie packs and a few others. I can't wait to play it with a few other people.
