We don't know what will be in the next GT game because it isn't out yet
I'm not talking about the next game. No one is.
I referred to Sport as in "sport mode" which appears to be their nomenclature for their online game mode
Which is also the direct title of the current game. You probably should have made that a bit more clearer. Not only that, but no one knows if "Sport" is part of the next game, because like you said, it isn't out yet, so no one would have made that connection.
It's fairly obvious that Sport mode will exist now as a component of future releases.
No, it's just a guess, really. We should just go off what we know, which currently is nothing.
Cross compatibility is being touted as a way of preserving a player base. Having two different online environments from GT Sport and GT7 would divide the player base too much
Yes, that's usually what new games do, have two different online environments. No new iterations from a game allow you to connect to players from the past game. You've basically confirmed what
@ARTAsean was saying.
Cross-console compatibility is a connection between 2 or more completely different consoles - Like Xbox and PS4. It like
can mean connecting to servers from past games, but it's usually used to describe connection between multiple consoles from PC, Switch, Xbox, or PS.
Backwards Compatibility is being able to play prior-generation games on the new/current generation.
My initial question is simply me wondering how they'll navigate that difference if they want to include weather.
That was answered. The game being backwards compatible isn't going to change anything about the game that wasn't already there in the first place. What is going to happen is you're going to be playing the game on the PS5, as if it was just a PS4(Pro, most likely.)
