Just had a look at Konamis latest financials for Q3 2015-16 they are pretty damn healthy and revised up their forecast for EoY... £25p/w for a editing job wont touch the sides. Tight as fuck.
I've read that the majority is from MGS and mobile, though, isn't it? Both of which now have issues (particularly mobile, they're apps that people download and enjoy for a couple of months and then don't bother with ever again)?
Could be wrong but the impression I get from most news sites is that they're struggling, and the F2P versions of PES sort of tally with that assessment.
Also, given how little of that profit is going to be PC/console PES-driven in comparison, I doubt any significant investment in PES will happen.
Knowing a little bit about the goings-on at the boardroom level of some publishers, I'd imagine Konami are thinking "we get 9/10 in most of the reviews worldwide and the game
still sells like shit, there's nothing we can do with this franchise to make it sell in Europe like it used to any more, so we'll just have to focus on the markets where it does sell, buy up all the Asian and South American licenses we can, put out a cheap-to-make game, and release a free version elsewhere to bleed as many kids dry of their pocket money as we can".
When Adam was asked about the popularity of PES in that BBC show, he mentioned "other markets" (Asia and South America specifically) a few times. Almost as if to say "it doesn't really matter if nobody in this room buys PES to me". Which, of course, they didn't, judging by the one-and-a-half hands that went up (thanks P34SEMM for the confirmation

)...
That sort of "fuck you, markets we don't do well in" also tallies with how little they give a shit about option files and editors - i.e. "we don't have your country's domestic league's license, so you're not going to buy our game, so we don't care about what it takes to make you happy" (though short-sighted, as it's a good way to provide a boost in sales, I reckon - a good option file is almost as good as a license, but admittedly, only AFTER you've bought the game).
They're buying up whatever licenses they can realistically afford and then focussing on those markets, because the licenses guarantee a certain amount of sales. In any country, if you can publish a game with that domestic league's biggest star on the cover, and next to it you've got FIFA with a random player from elsewhere - or even if they don't, even if FIFA has the same license and has a relevant player - you've still got a HUGELY improved chance of selling the game to Joe Public based on that alone.
