Yeah, its cool that they are playing chinese songs, especially This I love, that solo is very Slash-like!
I guess there will be more touring in 2017, it's been 30 years since the release of Appetite then. And hopefully with a new single or an EP out by then. It is also possible to finally release the Perfect crime documentary from the Illusions tour. There are still tons of unreleased Chinese-era recorded songs in the vault. I think they will either come out in a deluxe edition of Chinese democracy one day, or Slash/Duff re-record bass and some guitar parts on existing songs and put them out next year.
