New details about the upcoming portable rocker Guitar Hero: On Tour have been revealed at the game's official website.  The good news?  The Guitar Grip peripheral will work with the new hotness DS Lite as well as the old and busted DS Phat.  So, gamers with bigger fingers who might prefer the original DS to its slimmer successor can rest easy knowing they too can look like an idiot while playing the game.  The bad news?  The game alone is up for preorder for the low, low price of $49.99.  So, at minimum, publicly rocking out with a buddy in the game's co-op mode will cost a Ben Franklin... in addition to your dignity.
