I'm not sure about the specifics of the system but I know that Rubi Ka itself has 2 moons (they are named but I can't remember it and yes you can see them ingame, they're very large). It can orbit the two suns because the system is what's knows as a "Binary Star" (real science!); two stars orbiting each other very closely (literally only hundreds of millions of miles apart!) which effectivly create a single gravity well due to their closeness that planets can orbit firaly normally. I imagine this is the reasoning behind Rubi Ka (and Tatooine from Star Wars) being a desert planet: twice the suns means twice the heat (not real science. In fact, /sciencefail).
Anyway, back on topic I wonder if the new sky will be exactly the same as it is now, just rendered in DX9(ish). Because the one right now is good, but kind of smudgy. You could almost describe it as "low resolution" (though it's probably more complicated than the texture stuck on a mesh it's the same effect). A sky with clearly defined stars that twinkle and clouds that rush across it would be awsome.
