Nonsense: they just made some updates requested for NW, then decided to freely release the fixes and new operations from WFaS and NW development to people playing or developing Warband mods, as a gift (and then fixed things broken in Warband as well): to play NW you need to use a different executable to run that mod anyway, so Warband being updated was not a necessary requirement. The system is not "destabilized" just because a totally unofficial and unsupported hack doesn't work, which would be "broken" from the most trivial changes to the game executable.
That you are not getting regular status updates from taleworlds developers is quite normal: it has generally been difficult to get official statements and promises from them over the years, even when directly asking - as with game developers in general. The type of personality that makes a good programmer is often not naturally good at public relations (or at least don't enjoy it), and with a larger organisation probably most of the developers don't know the exact release plan, and the rest don't want to come out with public statements they will be held to in the future. Has anyone that wants to know actually asked a main developer directly if more updates are planned, via something like private messages or email? I doubt they read the forums much.
