It was established in the first roadmap of the year that details of new routes would be made in dedicated articles and not in the roadmap. Here is the quote for you: This last point is an important one. The Roadmap will no longer be the place to find out the new routes that we’re developing. Instead each new add-on will be announced independently so that it doesn’t simply get buried among everything else we’re working on.
I find this interesting though because they announced a new German route in the latest roadmap. I guess they mean they won't reveal the specifics like what route and what locos are gonna be in it.
Yeah, that's the impression I get, we had the same situation with Rivet's Luzern - Sursee route which was first listed on the Roadmap as 'Swiss Route' until an article gave us the specifics.
