That "World Tour" game is coming out, for the DS. Basically it is GH3 with 4 frets (with a special controller that hooks to the GBA slot), and you strum the touch screen with a special "Guitar Pick".
Also the next Guitar Hero game (before 4 comes out) is Guitar Hero Aerosmith.
BTW GH4 is going to cost about $200 if you want all the stuff (Guitar, Drums, Microphone, and Game).
