Guitar Hero: Aerosmith is being released in June of 2008.  I think this version is going hit or miss.  If you like Aerosmith this is going to be great.  If you don’t like Aerosmith you will probably pass on this one.  It will be interesting to see how well it does.  If it is a big seller I am sure we will see more.  I can totally seeing them doing a Guitar Hero: Kiss.
