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.
Guitar Hero 5 is already out.
NO.
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.
The answer is.... yes, but Guitar Hero has been postponed for 2011 only. In 2012, a new Guitar Hero game should be released. :)
PlOoP!
yes it is called guitar hero world tour is coming out in october 26 2008.
Guitar Hero 4 is coming out for the Nintendo DS not the playstation 2.
Never. Guitar Hero was hung up by Harmonix earlier this year (2011).
It has already come out
