The one thing I can relate to you is that The Undiscovered Country—according to Bryan [Fuller]—is a real sort of taking off point, or touchstone for how I guess he’s thinking about the direction of the new show. I don’t want to be misquoted and I don’t want to misquote him, but he’s fond of that film. Let’s put it that way.
That answer came off of being asked about the politics of Trek, in reference to both The Voyage Home and The Undiscovered Country. So while there are many different things you could take a direction from The Undiscovered Country, I certainly wouldn't mind a sharp commentary on the current state of global politics (or environmental issues for that matter).
Meyer was also clear to point out this will be a new sort of Star Trek:
I think it’s going to be a different Star Trek. It will go in a different direction. And I think that is probably good. Because the thing that mainly troubles me about Star Trek is the fear of it being maybe re-treads of itself. And to the degree that I had any influence on the thing [Star Trek] at all was that at least while I was there, we were fooling around. And if you’re not fooling around, then things can become stale. And I think that Bryan [Fuller]—who is a very clever fellow—has ideas—some of which I’ve heard—that are innovative and different. Different is what got me interested.Also discussed was Meyer's role in the show, and literary influences. You can read the whole interview on Den of Geek.
The new, as yet untitled Star Trek series, of as yet unknown setting, is due to start early next year. The first episode will air in the US on the CBS Television Network, but subsequent episodes will be available exclusively on the the CBS All Access on demand streaming service. International distribution has yet to be detailed.
