Actually, if you look at PS3Fanboy (PS3 blog from JoyStiq), the patch is being released this thursday, last month Sony persuaded Activision and Harmonix to make everything compatible for RB2 and GH:WT, and both companies decided that they should also patch current games (I think there is something about a GH3 patch coming out soon)
So I'm buying the GH:WT bundle, and RB2on disc, that way I'll have 2 guitars (RB1 and GH:WT), 2 Drum sets (GH:WT's is wireless, isn't it?) and 2 mics (I'll have to see which one is better, but they look identical and I need one for the downstairs computer anyway)
From,
Chris.
