It is taking much longer to release than originally projected, but I suppose it will be released eventually. I suspect that much of the hold-up may be due to the challenges of making all of the new add-on material work together without conflicts. Anybody who has had the game crash because of a conflict between mods (most of us) can appreciate this.
The original release date for 4.10 was last March. We are now 7 months behind that, I just hope it doesn't turn out to be a year overdue.
Good things come to those who wait.
