From my armchair I'll add that throwing away the KSP1 engine and replacing it with, based upon the number of bugs, a new implementation of the same basic idea seems like a terrible idea. My understanding is that most of the original Squad team (i.e. the only people in the world with experience building a successful orbital mechanics game) weren't kept on for KSP2. Take Two should have done everything possible to keep them as core KSP2 developers.

All that said, I don't think the game will be left unfinished. All costs are sunk and Take Two has a (reportedly) somewhat functional, nicer looking copy of KSP1 with, presumably, at least base elements of interstellar travel and colony systems in place. It's probably worthwhile trying to get the project over the last few hurdles, as it's a potential goldmine if they can pull it off.
