Led Zeppelin stateside in 08?

I just heard today that Led Zeppelin may be the headliners at the 2008 Bonnaroo music festival. This is big news indeed for a festival that hasn't been around all that long but is getting bigger and more popular every year. It may be the start of an interesting trend. Last years festival featured the Police in one of their reunion gigs. Who's next? Cream? That would rock so hard that it could never ever happen, but we can still dream.
