Sorry to bring your hopes to an abrupt end, but Guitar Hero has been dead ever since April 2011. That was the day Guitar Hero TRULY died, as the last month-based track pack was released that year.
People these days are still coming up with ideas on how to bring back Guitar Hero, and you can do the same.
There is speculation somewhere that two brand new GH games are supposed to be released this coming Winter season.
I sure hope that it's either a reboot or a sequel to WoR.
People are even coming up with custom setlists for a future game! You can do the same too!
Just hope to the God of Rock that there will be two new, and GOOD Guitar Hero games this winter.
