I'm just thinking of how they worded the Dual Entitlement for both Fifa And Madden because it's not the same for both.
Madden:
"Madden NFL 21 Ultimate Team binder content and Madden Points will transfer. Progress in
certain Franchise modes can also be imported from current generation to next generation. "
FIFA:
"All progress you make or content you acquire within FIFA 21 Ultimate Team (including players, items, coins, FIFA Points, match record, and leaderboard placement), as well as all progression in VOLTA FOOTBALL will transfer from PlayStation 4 to PlayStation 5 and back, or Xbox One to Xbox Series X and back. Progress within all other modes including Online Seasons, Co-Op Seasons, Career Mode, Pro Clubs, etc. will be specific to the console you are playing on and won’t transfer between consoles."
With Fifa, it seems like if you are getting Current gen and plan on upgrading right away, its best to only invest time on Ultimate Team since nothing else transfers over. With Madden it says certain franchise modes, so the best case scenario is that Face of Franchise transfers over and not regular Franchise because it is different on next gen
