It's true - it's been very quiet - especially if all we're waiting on is the save game function.
Last I'd heard from Chris Pope was back in April of this year.

However, that said... While I do think it's a nice idea... the toxicity of the Kickstarter page comments - (if that's what you mean by the "Kickstarter Forums") - I promise you, all they will do is bitch and scream, "We waited 12 years for this? THE SAVE FUNCTION DOESN'T EVEN WORK!" (or whatever other bugs that may yet creep up). So it's almost a Catch-22... You keep it, they continue to seethe, you release it when it's all good and done, and they will still seethe, but probably not as bad; or release the current state (which, mind you - once I knew the bugs and how to get around them - I loved SpaceVenture) - but those who have not been a part of the beta will rip it apart.
