It's put up or shut up time, either put an album out or just say your a touring band like Queen. Difference is Queen has lot more material to tour with unlike GNR who plays the same 30 songs.
There's always covers that can be added.
I don't think it's that dire for GNR. The band is out there doing what they like to do. Might put out an album, might not. They could probably say the same to you, put up or shut up time. You know, if they were listening to the puppet masters.
