Right, actual rumour time.
In
this article, in a discussion about whether Liga MX will be in the next game (it won't, says Robbye Ron—exclusive deal with EA), they speculate over whether Liga MX might be added as a fake league. The author writes this (Google Translated):
... in a conversation with a member of PESteam, it was confided to me that Konami's goal is to remove all fake leagues from the game, obviously with the exception of English and Spanish. Hence, it is up to Konami to analyze whether it is worth the effort to put the Liga Mex even if only partially licensed and do a market study to see if there would be a positive return. I would bet so.
The bolded clause sounds drastic, and the immediate interpretation is: remove all fake leagues! Meaning that the job of editors gets harder, and the joy of offline play gets reduced. But it may instead mean: remove facsimiles of established leagues ("English League 2", etc., not PEU league, etc.). In that case, they might also mean: sign up fully licensed leagues only, or else/also: add more fake (PEU etc.) leagues—in complete seeming contradiction with the text as written!
Honestly, it could well be second-hand, mistranslated, and speculative. So it's definitely not reliable, and even if it were, there's several permutations possible, each meaning something different to the future of the game, from offline and online perspectives. Online would suffer if they removed the likes of English League 2, nominally a "fake league" (offline would suffer too, if they didn't also add in extra, fake, editable leagues). But note the underlined clause above. Why is that "obvious"? I don't know. Could be that they mean: because they're very popular. But it could also mean: because they're unattainable (given EA's exclusivity deals). In that case, it points to the model of signing up whole leagues they can fully license, and not adding facsimiles of those leagues, with fakeish teams playable online.
That would be good for the online crowd. And it would potentially be good for the offline crowd, if they either added more licensed (and interesting) leagues, or if they additionally added more truly fake (PEU-style leagues).
