Well, it's about bloomin' time. But good news nonetheless. Harmonix have finally put out the long-awaited patch for (PS3) Rock Band that lets it use the Guitar Hero 3 guitar. And it works perfectly! Finally we can have two-guitar Rock Band (or even full 4 player if I had any friends!). Haven't actually tried it properly yet mind other than a quick test to see if it worked.
Now all I need is a GH3 patch to use the RB guitar. I'm sure it's on the way. Maybe.
And one thing's for sure, I'm not buying a second drum kit so they'd better bloody make sure the RB drums work with GHWT.
