Read on yesterday about it, unfortunently at this present time you have to buy the game stand-alone. If you buy on play.com the instruments pack will be £99 saving 30 pounds, and stand-alone game "30 saving a tenner.
I know where I'll be pre-ordering it.
Also, PS3, PS2 and Wii won't have this till sometime in summer, with that said Xbox360 will also have 9 Eur only tracks exclusively compared to the NTSC version.
Expensive game but will sell a few games to help pay for it like Burnout: Paradise, Rainbow Six Vegas 2, Assassins Creed. and perhaps GH2 or GH3 but not both as need one of the guitars in case I have 3 others round to play.
Been waiting for this baby for like year and a half that price tag will not turn me away now.
