Whenever a new DS peripheral is announced, there's a brief moment of terror for DS Phat
stalwarts, as they consider the possibility of being forced into an upgrade out of desire to play Arkanoid
(for example -- but that one actually does
work with Phats). Thankfully, Activision and RedOctane have not forgotten that some people like big DSes and cannot lie. The Guitar Grip made for Guitar Hero: On Tour
will work with both flavors of DS, according to RedOctane's preorder page.
More interesting news related to, uh, your decision about whether or not to buy this: RedOctane is bundling Guitar Hero
logo keychains with preordered copies of On Tour
, and also selling a $60 bundle with a case made to hold the DS and Guitar Grip.
