All of the info we have so far is that it's just eSports announcements, or at least it's eSports focused. I find that so weird.
Here, we don't care about myClub, but thousands do. How many people care about PES being an eSport? Surely it's a fraction of their audience?
That being said...
"The ball at your feet" makes me think that maybe there is an engine change after all. This isn't a vague comment, it's incredibly specific. If the ball feels better at your feet then at the very least, response times must be improved, right?
So there must be some kind of gameplay announcement too. There will be nothing to show in terms of gameplay (this isn't a PES conference, they're just making an appearance). But... There's something else happening.
