Estimated R3 release date
Wondering when you might be expecting to release the new version?
Welcome, Adam! That's a hard one to answer. The reason is pretty simple: the number of variables involved to get reliable timings is quite high. I just talked with Alessandro and an estimated release date should be likely in March/April (taking into account also the beta testing phase).
By the way: I like the internal policy that Kerbal Space Programs developers adopt because it's straightforward and the focus is always on the quality of the final product. In few words: "The next version will be released when it is ready."... their words, but I don't disagree.
