Looks like 10V is now confirmed. They posted another update to their story after passing 10K followers. Here's their screen shot of the milestone, except they edited the followers number from "10K" to "10V."
So it's at least a 10V PM2 based on the hints we've got so far. Now the big mystery is the reference to the scorpion.
REC also said in a comment "The 'REC' colors are reserved for the 204P. That's coming... eventually"
So, its not going to be the typical REC colors, flat dark earth blade and olive drab.
I was probably being a little ambitious guessing its going to be an Emerson Waved PM2.
Maybe it will just be a single tone, flat dark earth PVD coated blade and flat dark earth G10 scales?
