Based on what has happened in the past with other game releases, this is what normally happens:
(bearing in mind that just because it happened with other games is no guarantee for the future - and game subscription services continue to evolve such as with Game Pass, so this is a calculated guess based on past actions)
But EA games do tend to become available on the 'standard' platform (the 'vault' as they used to call it - and now EA Play (standard) linked to Game Pass) before a year has gone by - if the game didn't do so well, it could be a few months quicker.
I'm expecting MELE to do well, so I'd be surprised if it becomes available to Game Pass subscribers until well into 2022.
(personally I won't be waiting it out )
