I seriously doubt that there's real interest in anything beyond, perhaps, some remasters or ports. King's Quest was rebooted a few years back to not much excitement or success, despite being a fairly good treatment.
Space Quest I think is the one that might have the most potential if you did it right, but I still can't see it happening. I did love these games an awful lot back in the day, but I just don't see these names drawing in many old timers, and it saddles these games with expectations that are hard to meet while still making a game for modern audiences.
