Quoted from rubberducks:
I don't see why. Some of them will have had an MMr for at least 2 and a half years by the time any further production begins at CGC ... and closing on 3 years seems like substantial enough time for model revision / pricing change en lieu of scale and not having to pay a CM. Last run of Stern build ones was a while ago, too.
MMR won't drop in price, costs more to build 250 or 500 at a time than 1000
Same happened with woz 75th games went up in price.
