Robert Szeleney gave another update in regard to the development halt of SkyOS:

For the last weeks and as it looks like quite a few more weeks I'm in contact with a lot of people talking about their
ideas to continue SkyOS development. Unfortunately many people completely underestimate the amount of work required to manage a development team for SkyOS, either an open or closed source version, or completely lack vision and or motivation and or seriousness. Anyway, I'm still reading through my inbox hoping to get in contact with people with real motives and knowledge being able to bring SkyOS to the next level.
