Well in 2002 they were pretty big but not close to what they are now. I find it interesting that RHCP has headlined 3 times since Foo Fighters have been to Coachella. The Foos are bound to happen, I'd say sooner than later.

Jeez unless we get Bowie and Daft Punk the well has run dry

The Rolling Stones

Could headline, but odd fit for the festival:
I would die of happiness if AC/DC headlined
Jack White & Friends
Missy Elliott & Friends
Sigur Ros (upgrade)
Eric Clapton (odd fit)
12/1 Muse w/ Phantogram ~ 12/8 Of Monsters and Men ~ 12/17 CHVRCHES ~ 1/30 Nils Lofgren ~ 4/15-4/17 Coachella W1 ~ 5/13 The Cure
possible first time headliners...
Motley Crue reunion
Some shitty band I could care less about with some whining b as the singer
Some hippity hop act that again I could care less about (I respect rappers more than all techno 'beat makers')
a decent band that that couldn't draw 15,000 for their own show in their home town
Dip Set Reunion
Also Cut Copy WILL NEVER BE A HEADLINER.. and U2 won't headline anytime soon.
Will Pharrell William's hat make an appearance?
Bowie with guest appearance by Mick Jagger
