Update: EW has an anonymous source saying that, yes, people at The Jim Henson Company often talk about doing a Labyrinth sequel but that nothing ever comes of it. The site says “there are currently no plans to reboot, revive, or make a sequel to Labyrinth. It’s one of those legacy titles that is floated at most meetings, but, sadly, nothing is actually in development at the moment.”
