What happens to GNR if Axl were to die?
Axl is going to fake his death so he can release album after album after album and the record company can claim he recorded all the material over the past few years. He will get mass promotion for the first album once his "death" hits the media ... the album will be a success as will be all the music he releases "posthumously." Axl will not have to tour, because he is dead. This is a good thing because aged Axl can't tour/perform live like he used to and he sounds better in the studio anyway. Also, the new material will be so produced/layered that he would never be ever to play them live (Catcher in the Rye?).
Finally, Axl would rather be left alone ... but release his music too.
Great art is never celebrated 'till the artist splits this world.
Genius, that Axl!
