Don't be fooled by the title.  This is merely speculation, and at this point, would anybody even care about a reunion?  The story goes, according to Yahoo! Music, that original drummer Steven Adler spoke with frontman Axl Rose and reminisced about old times.

He commented: "I saw Axl, talked with him from 10 or 12 at night to 8 in the morning. We resolved a lot of sh-t. I said, 'You know the five of us have to get back together! That's when it will really take off again! Nothing will be bigger. It would be the biggest reunion ever in history.'

"He just grinned and giggled a little bit," said Adler.

The key to rooting through this quote by Adler is Axl's reaction.  When Axl Rose grins, it isn't a reaction to an emotion, but an involuntary result of the botulism in his face caused by the massive amounts of BoTox and whiskey.  If I was asked to bet whether or not Gn'R would ever reunite, I would bet on Wesley Snipes.  If that doesn't make sense, then rent Passenger 57.
