Could GTS servers still function for cross platform Daily Races and FIA?
Maybe PS4 users won't have access to GT7 offline, but could it be shared via loan cars/tracks online? I mean, if there is an FIA One Make at say, Daytona in a NASCAR. PS4 users couldn't enter because they don't have the car nor track on PS4. However, via online, they can connect and have access to that track and select the car. Is that possible? I don't know, it's why I'm asking.
Would the physics be/are we expecting physics to be that different from console to console?
As for PS5 GTS processing speed , as noted by Jordan, there is a difference. Would that translate to PS4 users versus PS5 users?
I get that Sony/PD want to sell PS5s. I get that. Just asking about the possibilities of cross platform play for online only, in such a scenario.
