I wonder how many songs they'll try to put on it? The biggest game now is 128 MB, Guitar Hero: On Tour will either be much bigger, or have all the songs in polyphone or whatever ringtones are... If I've got enough money, I'll probably get it eventually.
They should make it so you don't need the button attachment, like how you can use the 360 controller to play Guitar Hero II and II instead of the Guitar. It'd be cool if you could tap the notes using the touch screen.
