Let us explain. ... No, there is too much. Let us sum up. Guitar Hero III controllers don't work with Rock Band on the PS3. Harmonix made a patch to fix the problem, which never appeared. Harmonix released a statement saying that Activision "objected to the release of the compatibility patch," effectively halting it's release from Sony. That brings us up to yesterday when Activision released their own statement that they were (shockingly) blameless, saying "In fact, Harmonix and its parent company MTV Games/Viacom recently declined Activision's offer to reach an agreement that would allow the use of Guitar Hero guitar controllers with Rock Band." So, now it's apparently Harmonix's fault. Great. That's much clearer.
Tell you what. While you multi-billion dollar organizations are arguing like toddlers over a couple of toy guitars, we'll be over here being disgusted. Just tell us when you're done. Seriously, drop the he said/she said crap, do like Tim Gunn and make it work already, please.
