Ted Lange, Associate Producer on Guitar Hero II Xbox 360, told IGN that the final details regarding the game's downloadable content are still being ironed out but expect more than ever before.
"We're still in the process of confirming the final details and continue to secure more licenses, though nothing has been announced at this time, we can definitely say nobody will be disappointed," said Lange. "We are planning on having more online content than anyone has ever seen in a game to this date."
Lange also spoke of the wired guitar controller shipping with the Xbox 360 game, noting that a wire is needed to make it work. However, he does conclude that they hope to bring a wireless controller to fans of the game "rather shortly."
Guitar Hero II for Xbox 360 is scheduled for release in April.
