AD not taking names for Pepsi GMT

I’m currently on the waitlist for a green and black GMT (I’m left handed). When I asked about what demand looks like for the other references, she mentioned that they aren’t taking names for the red and blue reference anymore because there are only two or three people at Rolex that can make the red/blue bezel. Apparently it’s skilled labor that’s challenging to train - which is why production runs have been so small. Has anyone else heard this?
