The hope now is that a AAA single player games developer sees the gap in the market and caters to us, it's definitely not beyond the realms of possibility. In the short term we need indie game titles like active soccer who are at least trying to make an in depth sim because I think we'll be waiting at least 5-10 years for a proper successor to the PES series.
While I do expect a developer to step in at some point, the point of entry is very high. First of all developing a Football Engine isn't easy at all, even if you have experience with for example basketball games, setting up a Football Game engine is a different beast.
But even if you manage to develop a great engine there is the question of cost and licenses. Remember PES was way outperformed by Fifa regarding sales numbers in recent years and especially Triple A publishers in the current market expect certain numbers. Take 2k and the company behind it: they for sure wouldn't be happy if they reach similar sales numbers as PES, that would probably be considered a failure for the investment it would cost them (developing the engine and so on).
Which brings me to licenses, yes Edit mode is great and all but still the Casual Audience doesn't want to download Option files from a homepage onto a USB stick and then figuring out how to install it. While the NBA might be fine with you having an Option to download Rosters, the different football leagues wouldn't be. Especially Bundesliga has made it really hard in the past regarding even Option and Edit Files for example for Football Managment Games, which is why offering a download option would be out of the question. Which then again means Option Files and that is just a step most Casual Players wouldn't take (and you need them for your Football Game to really be a major success in the size that a Triple A studio would expect.)
Most Major Leagues have long licenses with EA and if you look at whats happening, the EA Logo is now even often shown during broadcasts of Premier League, Serie A, La Liga and more and I expect this to become even more.
So this makes it already very hard to compete because even if you can get the FifPro license, having the real experience and teams will not be completely possible.
And as PES has shown, while Gameplay can be a good factor for you as a Football Game, the situation has changed compared to the earlier 2000s where this was a bigger selling factor. Nowadays Licenses have become way more important than they were in the Nineties and 2000s.
So it is not out of the question that someone new might want to show up and compete, but there is a lot of obstacles in the way of success, so I am not sure if someone like 2K really would take the plunge, knowing they couldn't have the Major Licenses, that they would need.
It might be that when some licenses are ending, that they then would step in and get in a bidding war, but for now if new companies show up, I see them mostly going the same way Efootball does, since this way you mostly just need Fifpro and have a way safer bet.
