Guitar Hero: On Tour

when i first saw the above image my first thoughts were "awesome! what an idea", but after examining the image a bit more and letting it sink in, i start to think "well, its only a little bit bigger than the GBA slot itself, how comfortable is that going to be?", and i believe that to be a pretty legitimate thought, i mean, pick up your DS and put your 4 fingers on the ds lite and pretend to play, doesn't feel too great, does it? of course, this is all speculation right now, we'll have to wait until Summer '08 to get our hands on it.
