Weekly changes sounds more fun indeed. Still I wonder if it will be in-game transitions or since the world is persistent (unless they do it in a client peer-to-peer kind of way) we get these weekly server maintenance windows where they can change the season.
If the size of the map is that important I can highly recommend The Crew 2.
I pre-ordered it as well, can't wait to start playing it again.
Back to FH4, on the car count of "over 450 cars", FH3 was announced in 2016 with "over 350 cars" but ended after the content and DLC updates with exactly 525 cars (including Horizon Edition cars, which I assume will return for FH4). It would be so nice to have Toyota and Lexus back and finally have all the big brands together again, that's already been since FH2/FM6.
Already really nice to see our requests for custom routes being answered.
Yeah FH3's map felt smaller than it actually was IMO. On one side of the map you can blame the outback where you can just go from point A to point B in a straight line. And on the other side of the map you have a dense forest where you basically don't have much other options than following them. In the UK I assume we will see a lot more farmland, farms, hedges and the likes so it will feel different I think.
I hope we also go back to the 5+ cities from FH2 instead of the 3 cities from FH3. That was also one contributing factor to make the FH3 map feel smaller or get bored with it more quickly.
