Mega early pre-order set as 17/10/08 I know, but when you consider the PS3 and 360 versions are pre-ordering at £62.99 at Shopto and the existing PS2 Guitar Hero III with guitar set is £44.99 at shopto - it sounds a pretty good deal for those who still buy PS2 games or specifically want the PS2 version
If using £2 off voucher and quidco price should go down to £34.55. Maybe worth a pre-order now - which you can always cancel at a later date if the specs aren't to your liking(i.e. wired OR wireless guitar controller issues etc).
"Guitar Hero World Tour
Guitar Hero World Tour delivers more ways to play than ever before. Virtual musicians can live out their rock and roll fantasies by playing either a single instrument, or any combination of instruments, in addition to the full band experience. "
