I believe porting is often outsourced to another company. I figure Sega could make that happen if they wanted to. In fact, I wouldn't be surprised if that is happening right now, but even porting takes time. It might be happening, but they wouldn't tell us til the release date is near.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
