Duff McKagan Joins Axl Rose On Stage - Does It Matter?

Last night, Duff McKagan joined Axl Rose - and the rest of Guns n' Roses - on stage in London. The show was the first time Rose and McKagan shared a stage in 17 years. So what does it mean?
McKagan helped out GnR with a few tunes including "Nice Boys," "You Could Be Mine" and "Knockin' On Heavens Door." Of course, this performance immediately kicked all those GnR reunion rumors into high gear. Again.
I say, "not so fast."
Sure, anything is possible but maybe everyone is reading too much into this McKagan-Rose merger. Maybe everything wasn't as tainted between the two as we've been led to believe?
Axl has made it very clear he never wants a full-fledged GnR reunion because he doesn't like Slash. To be specific, Rose told Billboard "What's clear is that one of the two of us will die before a reunion and however sad, ugly or unfortunate anyone views it, it is how it is. Those decisions were made a long time ago and reiterated year after year by one man."
So, while Axl is apparently getting along with Duff now, I'm not getting my hopes up for much more. Axl has a new version of Guns now, and that's okay. He owns the name and the other ex-Gunners have moved along with their collective lives. I'm not saying I wouldn't love a reunion - and I think it would do gang busters in ticket sales - but I just don't have the faith it's going to happen. At least, happen anytime soon. I would, however, love to know the back story behind this Duff-Axl surprise performance. I mean, who called who? Was Sebastian Bach involved? I read online that Axl and Duff were staying at the same hotel and they sort of "bumped into each other." That seems far fetched to me, but whatever.
What are your opinions?
