Just some background on that new guy.
Name: Josh Klinghoffer...he's played on loads of Frusciante's solo albums, contributing drums & vocals among other things. He's toured with PJ Harvey, Gnarls barkely and loads of other bands.
He also has his own band called Dot Hacker where he sings, some of their songs are on youtube. They will also release an album sometime late next year/early 2013. (Based on RHCP's current touring schedule).
Also, i thought One Hot Minute was fucking dope, and i'm a huge frusciante fan.
