Regarding the drummer, Frank Ferrer is drummer for 2025. There is an open invitation for Matt Sorum to be a guest if and when he wants, apparently.

And there's nothing happening this month musically speaking. They're all at home having a break until after New Year. Duff played some charity gig last week

It'd be better to have new material, then revisit this further down the road. Chinese Democracy is known as the album that took alot of time and money to make,  and continuing to release songs from that era is just contuining that story. I think they need to move on and start a new chapter

Livenation organise the tours, they were waiting for Duff to finish his solo tour, agree the dates, then announce.

The band are on a break so anything musically speaking starts now going forward. They are thinking about it, that is all they are saying both privately and publicly

The European tour is real, it should be announced next week, as per the news stories. They're looking at US dates for Sept, Oct time. There is new material, but as of two weeks ago, they're were no plans on how and when this might be released.

From a recent Loudwire interview with Slash

"I'm going into the studio with the Conspirators, getting a new record done and then after that, 2025 is all about Guns N' Roses," he said.
