Don't you mean a bluff? A double bluff would mean he wants people to be disappointed when he isn't there come April. Tell the truth when people won't believe it. Not nitpicking, just checking to see if I get the meaning correct.

I don't see a bluff or a double bluff making any sense. Making people think you aren't coming when you actually are is something Axl or Slash could do. Izzy wouldn't get nearly the same response to justify not promoting this as a bona fide reunion, merely for the sake of some last minute reveal. And a double bluff would just make the fans disappointed when he's not part of it and they thought he was.

To me Izzy is telling it straight like we would expect. And that means this isn't really a reunion at all. Axl just needed a few replacements in GN'R, and Slash/Duff happened to be available. Notice how he isn't saying he's not involved because he doesn't want to, he's just informing us he's not involved. Maybe Axl never called and this is his message saying "hey, I want in on this!".

Or he didn't like the terms and said "fuck this I'm outta here", then goes on Twitter to squash false rumors because he cares about the fans.

Makes me realize it doesn't matter what anyone says in GN'R. Fans will interpret statements any which way. Because we have gone so many years with just loose rumors and innuendos, conflicting statements, scams and plans that never panned out. Even a confirmed, direct statement made by Izzy personally is met with: nah, not buying it! 

Where is sp1at when ya need him most?

So basically a tour is already set in stone but we are just waiting for the actual announcements?
