I don't know why Konami had to introduce even more versions last year. It was bad enough having a Pro Evo UK/EU, Pro Evo US and Pro Evo Asia/JPN (W11).
You'd expect them to at least create a common system to enable universal functionality of OFs (given the licenses restrictions) but they keep adding more versions.
As of now, officially we know there will be EU, UK, US and W11 (just like last year) but who knows? They might just add a Eurasian, Middle Eastern, French Polynesian and Maori just to mess with us.
