It might because more new things exist in those games then old. Using the same engine doesn't always mean you get a game faster, they can use that extra time to change more, add more etc. As in, it might not take as long as the first time based on designing an engine, doesn't mean they'll cut corners for sequels either.
So none of the games being talked about to my understanding are using the same worlds as in levels.

who knows, if we see some massive trailer and gameplay demonstration early in the year after Horizon 2 and GT7 comes out maybe it is indeed a 2022 title, but if they keep with a teaser or something, maybe it really is a 2023 game, its hard to tell with that one tbh.
edit. oh yea I forgot we did get some trailer of it. Yea thats a big maybe. I think it might be on board for a 2022 release indeed as a few things.
1. We did get a trailer
2. its cross gen, as in it looks like it was made for PS4, plays on PS5 type thing.
3. enough in trailer points to lots of it being pretty near complete like the overworld, gameplay elements, I'd maybe be on the fence if it was just some teaser with a voice, but it seems like 2022 might be a pretty solid time frame, but again wouldn't be shocked if it slipped into 2023 and wouldn't mind if it was to get a solid title overall.
