Yes. Just go to Guitar Hero 3 .com and look for Guitar Hero Online.
You could look it up, but there are, so far, three different Guitar Hero games for the Nintendo DS. Guitar Hero On Tour, Guitar Hero On tour Decades, and Guitar Hero Modern Hits. If you need more info on them, look it up.
If by guitar hero 4 you mean world tour the answer is yes. go into the xbox live marketplace and look around.
As I am speaking from experience, I believe this is true! I was once challenged to a Guitar Battle on Guitar Hero by a friend who was a pianist. I am naturally a guitarist so you would expect me to have some kind of advantage. However, because Guitar Hero requires you to not look at the guitar while you play, you have to "guess" where the buttons are and hit them quickly. Therefore, playing guitar makes you worse at Guitar Hero.
Guitar hero because look at the drums it looks more like the drum and you can play with more people.
Yes they are but they changed the name to guitar hero world tour but it is still 4. It will also have drums and a microphone like rock band and you can even create a rocker and a guitar. for more info look it up.

I don't think anyone knows yet about GH4 controllers. They still haven't even released standalone controllers for Guitar Hero 3 or said if Guitar Hero Aerosmith will have a special controller. There are, however, new controllers coming out in March. Check out the related resources below to take a look at the new Guitar Hero controllers coming soon, they look pretty sweet.

i think guitar hero 4 is better cause guitar hero has better instruments and rock band has crappy instruments and a crappy same look and guitar hero has better songs than rock band 2 so their you go
Websites such as amazon and ebay are good places to look for used Guitar Hero games. There is also a Guitar Hero community linking fans together that may be willing to part with games they are no longer interested in playing.
