Axl Rose is currently rumored to maybe make a new album with AC/DC and Slash just started the promotional cycle for his new album. Neither of these things are new Guns N' Roses, but we're still not ruling out the possibility of a new album.
In an interview with Iceland Magazine, Rose says "Right now our focus is on touring and the shows but everyone seems to be getting along so you never know."
For all we know, Guns N' Roses could be working on new material as we speak. These dudes are touring non-stop, meaning they've got more than enough time to soundcheck and maybe fool around with some new riffs here and there.
