Recently I got a email about a new fh5 update and it's one of the biggest updates so far.
Here's the link to the official blog post about it will tell you all about the update. https://forza.net/news/forza-horizon-5-horizon-realms#msdynmkt_trackingcontext=00b30855-c996-4812-b134-9aa8ec870100
Also good news is forza horizon 5 premium edition pre-orders on PS5 now give you early access to the game. But it's only premium. Standard and deluxe dont give you early access.
