In the face of Rock Band, Activision seemingly has an uphill battle on its hands with Guitar Hero III. As one of our blogging buddies on Joystiq put it, "if you have Rock Band and a guitar, you already have Guitar Hero." Naturally, the addition of more instruments would seem to expand this value even further. According to Activision Senior VP of Marketing, Will Kassoy, however, Guitar Hero III is not down and it's certainly not out. First of all, Kassoy notes that Harmonix (developers of Rock Band and previous GH games) are experienced in software, not hardware. In other words, the Rock Band peripherals may not stand up to the standards set by Red Octane. A little more on point, Kassoy notes that the two games are likely to have a very large price disparity, with Guitar Hero III on the winning end of the spectrum. This makes much more sense, although it's somewhat mooted by the fact that Rock Band will support Guitar Hero II controllers. Still, there is no denying that the cost of entry for GHIII is lower than aiming for the full experience of Rock Band, and that may work in Activision's favor.
