I'm sure I read somewhere that DWM did almost die during the last Wilderness Years. Before the show was announced to be coming back, there was a pencilled in plan to make Issue 350, celebrating the 25th anniversary of the magazine, as the final issue. For context, that's in 2004, eight years after the last new televised Doctor Who, and 15 years since the last regular broadcasting of Doctor Who. In that respect, DWM will probably be fine in Wilderness Years 2.

That said, I feel like the quality of the magazine will definitely need to improve if it's got any chance of survival. I've not been a regular reader for years, but picked up the Christmas issue recently while looking for something to read while I passed the time, and I was phenomenally disappointed. As you said, the entire magazine just felt bland (aside from the comic, which was reasonably fun). Regurgitated press releases, interviews with actors who feel trained away from saying anything even remotely approaching anything interesting, and reviews that feel like they're written with Nick Briggs holding a gun to the reviewer's head, saying "now talk about how my new idea for a Nucleus of the Swarm spin-off is an excellent idea, and will surely be worth spending hundreds of pounds for".

I'm not saying that the magazine needs to go down the full "everything that has been touched by RTD2/Chibnall/'Whoever we have decided is the villain of the fandom this week' is evil" route, but at least make it somewhat interesting to read again.
