Speculation is just that - and without credible sources the pink floyd rumour is just about as substantive(ish). Also speculation is bound to surround GnR because of their history. Essentially, you can make anything up and attribute vague or unspecified sources and it's all meaningless. assume GnR will play until it's either confirmed by the band or organisers.

Exactly what I was getting at.
Rumours are rumours and unless you can give credible sources to back up any speculation you have then unfortunately you don't really have a pot to piss in. Walt Disney's head is being preserved in cryostasis, Elvis isn't dead but Paul is, and Phil Collins is an anti-semite, etc - all "true" if you believe the sources you cannot provide.
If a band as big as Guns N Roses were to pull out, they'd need to do it now and Festival Republic would need to announce it now so that people have ample amounts of time to decide whether to still go or not, and like I said, so long as that line-up poster says they're on the bill, they're on the damn bill and they'll be ending my summer with a bang.
