Can someone give me the logic of why the developers would want to allow people to import their previous saves onto PS4? I can see very little compelling pressure to allow cross platform import.
By all accounts, ED is a grind game. A good grind game, but a grind game. You do things, hopefully get a bit better, which lets you do more things. Depending on how you do, you will get to a natural ceiling at some point and will start to focus on other aspects of the game.
Once a percentage of commanders get to this point, a number of them will stop playing (and stop paying for store items such as decals or future upgrades)
By allowing commanders to transfer a save across that is already a certain distance down that path, the developers will be accelerating people to that point.
The only reason(s) I can see why they would allow for game save import (even if it was technically possible) would be to either entice commanders to move off of problem platofrms (PC, MAC or Xbox) or because they felt that the take up on PS4 would be low.
But I don't see either of those two drivers being particularly strong
