I saw this thread was active and thought there were finally some updates on that 3rd album. I guess there won't be one?
So I actually can remember exactly where my comment from 2020 came from. After the Haken/Devin gig in Philly me and a bunch of the Haken guys went to a local place for food, and Charlie was texting with Pete Rinaldi (who filled in on bass for Haken) and was talking about working on the 3rd Headspace album. Of course that was right before the pandemic hit, and it wasn't the most active band to begin with. So it certainly could be easily delayed, and who knows, it may never happen, but I can say with certainty that a third album WAS being worked on at that point.
