Let’s see before we start making wild guesses. You haven't even seen it! Making a comparison with Daytona is a bit exaggerated. Unlike Daytona, I am sure almost none outside of OF cares about SS 321. For majority of potential customers it will be just another hand-wound Omega. Until it earns status of Daytona at least a decade would pass.
And while you claim disappearance of 50th SS that is again a wild guess, and even if you have insider info you may just claim they are sold in. The same was the situation with Speedmaster 60th, and turned out that even as of today one may find it sitting with OB and AD. So sold out is quite different from sold in.
