It's simple: While you are asking me to give you more information, other developers get hell from their community because they can't keep announced release dates (for whatever reason. I'm not judging them because I know the work that is involved. If it takes longer, it takes longer. It won't kill anyone). I don't want this. Just look at what happens in the Fenix Discord right now (after they announced the delay of their Block 2 update) and you will understand why I'm going with "It's done when it's done". I'm not a friend of creating hypes or posting WIP screenshots every other day. Expect to see screenshots and more detailed feature information when we're well into beta testing.
I promise you that there will be a CRJ update, although it will likely not be released before the end of the year, that it will be a major one, that it will include the much awaited LNAV/VNAV fixes as well as Simbrief, Navigraph Charts, an updated model with a detailed cabin and more.
