Surprised no one else here on the forums has brought this up just yet (or if they have, there's not a dedicated thread to it), but today, Mark Crowe and Scott Murphy have officially announced that they are back together and teaming up for a new game!

They DO NOT have a KickStarter up, but it wouldn't surprise me if one appeared sometime down the road. Currently they are hiring, looking for narrators, and mark the 3rd notable appearance of former Sierra legends coming back into the fold. With Al Lowe, Josh Mandel, Jane Jensen, Robert Holmes, Mark Crowe, and Scott Murphy all announcing their returns to game development, could Ken and Roberta Williams not be far behind?

So with a tentative title of "Two Guys Spaceventure", it's looking like we might just see another Space Quest game (or a spiritual Space Quest successor) in the very near future.

I know I'm excited! :D
