I don't know, I have mixed feelings about the game now from what I see. Usually I am the one who leans to Konami side and I even found PES 2014 a good game, on PC, considering some adjustments are made and before latest patches. I liked the turn to a more simulation approach, which sadly got less and less apparent with patches.
Now from the Youtube video's I see lots of arcadish running, which even having in mind the abysmal kick and run style players, seems like a step back. Defences look wide open, there is no compactness, and AI defence, let it be on Regular, seems still bad. Gamersyde videos forutnately look much better as youtube is known for making the game seem faster than it is, and that keeps my interest in PES 2015. I don't agree with Klashman about tactical side, which for me is improved and more intuitive (after all, who needs 20 degrees of defensive line and pass lenght?), so I look forward to it.
Now those news about PC version somehow put me down, as I play only on PC, but I will check it in any case to see how possible is to simulate football with PES 2015. Because watching FIFA 2015 videos I feel it's still far from football. It's very gamish.
