I'm going to make a prediction here that due to the number of units the Speedmaster will not sell out that quickly but will be hard to source after a year or so similar to the CK2998 and will be available at or below MSRP at some point.
The Seamaster I'm thinking will take a fair bit longer to sell, and the Railmaster (which I really want), due to its lack of awareness and features will be a slow seller, and should be available at a decent discount eventually, at which point I'll hopefully be in a position to pick one up maybe next year or something. I have a feeling that Railmaster might actually come down enough to really be good value in time, and would be a superb daily wearer.
