Straight from Leipzeig (or however the hell you spell it), Rock Band is delayed until 2008 for PAL systems because they're localising the track lists for each region, so we'll get some local music to rock out too.

Also, some new tracks announced, all originals:

Rolling Stones - Gimme Shelter
Deep Purple - Highway Star
The Clash - Should I Stay or Should I Go
Faith No More - Epic
Smashing Pumpkins - Cherub Rock
Radiohead - Creep
Beastie Boys - Sabotage
Jet - Are You Gonna Be My Girl
OK Go - Here It Goes Again
Nine Inch Nails - The Hand That Feeds.

this game may just be the thing that finally makes me cave in and get a console

Well that sucks and is good at the same time. Any idea what month next year?

Rolling Stones - Gimme Shelter
Deep Purple - Highway Star

Fkn A! I'm loving the whole competition between Rock Band and Guitar Hero at the moment, each one trying to be more epic than the other!

and fortunately, you're not tied to one console system
