With small updates and some improvement just to cash in more money they are already doing this by making Guitar Hero: Aerosmith they are even making a ds guitar hero(lets be realistic the ds does not need guitar hero it already have amazing games).

Of course they will.

DS Guitar Hero??? That'll be uhh...interesting..

Yes, the question of a big company not milking a successful series is not one that needs to be asked these days (cough.. need for speed)

yes....but who isnt going to buy it?

Activision is the new EA, of course they'll milk it dry.

Guitar Hero DS will flop, I'm sure of it. It seems like a game that would be made for the DS (now instead of a guitar, you can just tap the onscreen dots!) but it's just stupid.

Anyways, it will be released so often that at one point it'll just become a mainstream piece of crap. I think Guitar Hero 4 will probably be the peak of sales for the series, and then you'll see Activision putting the series on the PSP and DS and Cell Phone, and god knows what else!

DS could work well if you could actually flick the strings on screen

They'll try to, so far I've only bought the 3rd one.

Guitar Hero will turn into Smackdown vs Raw
or Madden.
