Unfortunately yes, Activision canceled the series, after they started losing money on it. They first discussed it, when other versions were released e.g. rock band.

Activision.
Guitar Hero is made at the Activision studios I would assume.
Yes. all guitar hero instruments, for the same system, can be used for other Guitar Hero games/Music games also from activision like Band Hero.
Guitar Hero is dead because of the declining sales in the Music Game Genre. Guitar Hero: Warriors of Rock was supposed to be the last game in the series developed by Neversoft, with future installments done by Vicarious Visions, who handled all of the Wii versions of Guitar Hero since Legends of Rock, as well the Guitar Hero: On Tour series. However, because of the declining sales, Activision closed down its Guitar Hero franchise unit sometime in Feburary 2011.
As of 2009, no, but if Activision is smart, they will make it available because it is the best full band Guitar Hero.
It depends. Harmonix created Guitar Hero 1, 2, and 80's. RedOctane/Activision created Guitar Hero 3, Guitar Hero: Aerosmith and Guitar Hero: World Tour. You can tell the difference by the graphics pretty much.
no, and it's Neversoft, not Activison
