Obviously, I'm not affiliated with EA, I'm not a developer, nor a "Game Changer" so I honestly wouldn't be able to definitively confirm it for ya, haha.
But what I can assume is, yes I suppose so. Although, in my eyes, it seems they've gone for a very basic upgrade without specifically considering next-gen or anything.
Unless otherwise stated, I'd assume so! I would be aware of the fact that the crossplay could run into logistical issues though, considering you'd be playing on PS5 as a PS4 player, or the remaster might be ported to PS5 etc...
I am hoping for some sort of open world. But again as said, that wouldn't be in line with the original.
I am curious about wheel support though.
