B - Memory is a 'class of product', DDRx is just the model. A few people will buy the 2022 Ford-Model-X for a premium at launch, but once they've bought it, Ford are just selling to the people with a 2010 Ford who just want to upgrade to what's in the new catalogue. I'm sure some of those upgraders will pick up a bargain on that onsold 2020 stock - but Ford aren't devoting resources to keep making those old models.
