I'm still a little confused by this "upgrade system" that games are using.
It's different than just giving it a next-gen patch, correct? It's a second SKU.
So, what about things like the trophy system?
Say I completed the campaign on the PS4, and have like 40% of the trophies. And I bought the DLC.
Now I upgrade for the PS5, and play the DLCs on the PS5, using my PS4 save.
Where do my trophies go? Will they have a separate trophy list just for the PS5, and so I have trophies for one thing on a PS4 list, and trophies for another on the PS5?
