John's return to RHCP hasn't been as good as expected IMO. The two albums that came out last year are OK, a bit too bloated, but there's good stuff there. I just expected better I think because the previous albums with him are their best. Josh was fine with RHCP though, those two albums are just as good as the two new ones (if not better).
Can't gauge MP's return until they do something.
But like Stadler said, it's really not an apples to apples comparison here.
I had mentioned Bon Jovi's situation as a comparison, which isn't quite apples to apples, but I think it's better than this comparison.
Here's another interesting band change just announced yesterday....Rome is leaving Sublime with Rome likely because Sublime is going to go with Bradley Nowell's (the original singer/guitarist) son instead and go back to just being "Sublime". Defininitely not an apples to apples comparison either, but interesting to think about how this went down.
