From the perspective of a software developer I see no real issues here. The thing is that Larian wants to deploy builds that are stable obviously, so they cannot simply push anything they work on it into every new patch. This is why a lot of things seem to move very slowly (aside from things like graphics and very general systems).

Obviously this could mean that they dont do anything, but for now I do hope that this is not the case. Because simply implementing things onto the existing system would not be that difficult, so the slow pace seems to be an indicator for a lot of background work.
