The thing I guess I'd be most worried about, is how long PS2 will be available, and what features you can lose by not having it on another system. By no means am I saying go out and get a Wii, X Box, or PS3, but even though I already had Guitar Hero for PS2, I asked for World Tour for the Wii in order to store made up songs, and download more songs and whatever else. I guess it's a tough call, I appreciate that PS2 isn't forcing you to buy a new system right of the bat, but with PS3 available now, you'd think PS2 would become obsolete in the next 6 months. It's very similar to when Nintendo introduced Super NES, imo. Also, I haven't gotten to play the drums for Guitar Hero, but being a drummer, I liked Guitar Hero's drum set up much better than Rock Bands. The pads are fairly small on Rock Band, and from left to right it goes something like Snare, Cymbal, Tom, Cymbal. Which isn't really how drums are set up. Guitar Hero installed the cymbals above the drums to give you a better sense of playing real drums. Again, I can't confirm the game play on the GH drums. Just what I read and saw.
