I remember first seeing those pictures in a dev-stream, and gawking instantly, even in that early iteration, they looked fabulous. I think that Squad is going to firmly rooted in developing Career mode until it is done from now on, and then overhaul the aerodynamics system (along with art passes on all the spaceplane parts) when Career mode's infrastructure is basically completed. Then I think that will be the time for heavy optimization, allowing far more celestials to be added to the game, along with the discovery mechanic. That's just me speculating however, don't quote anything, just seems the logical way to do things IMO. I don't think we'll be seeing resources for a good-long time, and they'll probably fit in tweakables with one of the coming updates. This brings me to another point, after Career mode is finished, which will only take a few updates (I sincerely hope), isn't the game feature complete? Are our glorious alpha days coming to an end? Harv himself said that resources and colonization were slightly out of scope, once Sandbox and Career are both finished it seems like the game would only need polish and small additions...
