How Long into 2018 do you Anticipate Rolex will continue producing the SD43 50th Anv?

I don’t think they will remove the red line anytime soon, however they may adjust something such as the typeface, kerning/leading...some little detail... then the first iteration aka the Mark 1 becomes more valuable than the second iteration, then if a Mark III comes out, the mk2 becomes more valuable as well, etc... Right now the MK1 sub 50tn anniversary are selling for much more than the other ones...
