While making moves like limited editions in a certain ammount (which would lead to the question when it is still limited, but that´s for another debate) can make sense, it would not by limiting the general availability. Nintendo can get away with it for the 3D All stars collection, but that is a brand for itself which is stronger than maybe anything else in gaming. So limited editions would make sense but this is happening anyway with almost every major title. A broader approach of this strategy would lead to nothing.
But (there is always a but), the ideas behind moves like limited editions, approaching the given subject (which is gaming in this case) as a lifestyle is something that Sony is obviously applying already. The pre-orders went down as Kind of shock drops, a very "tight" (to use an euphemism) communication with the consumer, scarcity, strong emphasis on influencer/celeb personas within the relase strategy (travis scott, geoff k.), etc. all of this reads like the how to create a hypebeast (and i mean that explicitly WITHOUT the negative connotation the word has meanwhile) lifestyle brand 101, which every second fashion and music label tries to do.
This approach makes even somewhat sense, given sonys history as a general manufacturer/provider of consumer electronics and helps to position the brand against competition that has either its service (xbox) or its nostalgia and general brand loyalty going for it (nintendo). And as of now it seems to work, because demand for a next gen machine is pretty damn high.
