Last update to O:G was May 20th. They've previously worked in 2:1 cycles for Claire's Quest and Overgrown: Genesis. June was CQ, July was CQ, next update should come around the end of August. Assuming the 2:1 cycle hasn't changed, that will be for O:G. I doubt Architect is going to abandon O:G, but it's possible if the team gets close to finishing CQ that they will put O:G on hold for a little while.
I checked the Patreon page to check to see if they changed their update schedules, but I can't find the line about the 2:1 schedule. O:G is still listed as an active project though, so I wouldn't worry about it.
