Nothing from SHOT Show (yet) but I just checked the Marlin website, and it is is now showing "Early 2023" for the 336 and "Spring 2023" for the 1894. That is a relatively recent development I think, because I've looked at the website in the last few weeks.
Soon™
If they release a threaded 1894c, I might buy one from Ruger, transfer light mount, sights etc to the new one and hold the Remlin in reserve. A couple months ago I could have sold the Remlin on Gunbroker for 2x to 3x what I paid for it, but I bet as soon as the Ruglins drop, the value will plummet on the Remington era guns.
