Comparing the Wii RB2 with the PS3 RB2 andf I have to say the PS3 version guitars are more solid. I have had the PS3 for a while so have up until now gone for GH1, 2 and 3 and RB, but my in-laws have bought a Wii for Christmas so I was tempted to get RB2 for it.

Don't think I will - but I will get Super Mario Galaxy :-)
