I would hazard a guess that the 'PS5 features' are to do with the haptic feedback and adaptive triggers on the dual sense, which are features of the PS5 obviously not on the PS4.
It has.
You missed my point though. To me it seems odd that Sony explicitly highlights PS5 features for GT7 when it is only announced for PS5, whereas HFW, which they have announced for both PS4 and PS5, doesn’t mention the advantages of the PS5 in a similar way.
One would think that “PS5 features” are most relevant to point out for a game coming to both systems, and maybe it’s an indication that GT7 also will be announced for PS4 down the line. It’s a stretch, but still interesting nonetheless.
