Additonal Info:
A rumor was swirling around the interweb last week that Activision was delaying a patch for the PS3 version of the recently released Rock Band. The patch would have allowed for compatibility with Guitar Hero III's Les Paul guitars, a feature desperately wanted by PS3 gamers.
A week has passed, and it appears the rumor was indeed true - Activision is preventing Harmonix from releasing the patch, which has been ready since December 4. Harmonix recently released a statement regarding the matter.
"As is the case with the Microsoft Xbox 360, we believe that Sony PLAYSTATION 3 users should be able to use the peripheral of their choice with Rock Band," said Harmonix.
"We sincerely hope that Activision will reverse its decision and allow release of the compatibility patch and further, that Activision will allow Guitar Hero III to support Rock Band guitar controllers as well. We welcome all third party developers who wish to support our controllers and will provide any required support in order for them to do so.
"We believe that when consumers have choice, everyone wins. Harmonix and MTV Games hope that Activision and others in the industry will also adopt this philosophy."
We as gamers hope that Activision does indeed back down and allow the patch out to the public. More on this topic soon.

Well that sucks i just got that game today but its cool cuase dont even have the gutar hero 3 guitar anyway....
That really sucks. Hopefully they;ll get this resolved soon
Hey Activision.....RELEASE THE PATCH AND STOP ACTING LIKE JERKS!!!! You guys develope 1 G.H. game and you think you own everything?! Gimme a frickin break.
Rock Band > Guitar Hero 3. I don't even need to worry about it because I'm not buying Guitar Hero.
Greedy SOBs. Does anyone remember Namco complaining about they're Guncon controller? I don't. WTF Activision, get your act together.
Didn't Red Octane said a couple of days ago that they did not want Harmonix guitars to work on their game as they were to buggy? I guess Harmonix got mad at this comment and is now releasing the truth, greedy Red Octan does not want the compatibility to work either way...
Its so stupid, its not like activision will loose money if GH3 controller works with RB, if anything Harmonix wouldn't make as much money on additional controllers
Well I guess im not going to get any guitar hero games I guess theydont want my money I suggest nobody else buys their game unless they release the patch
psn id: gingo.. activision are being right nobs about this if something isn't working as it should a patch should be released but activision are too gay to release hope they die in a fire
Didn't buy a GH game or RockBand. Good choice on my part.
Sounds like bad blood on both ends.
Give it some time and the bad press and public outcry will get to them.
