Reports coming down the wire suggest that fans who had been eagerly anticipating PES 2009 for online play are currently very worried. Many are claiming that most games they play online suffer from lag as PES 2008 did last season.
If this is the case then it would be extremely disappointing for the PES community who were unable to play online last year for the same reason. This problem has been found on both Xbox 360 and PS3 versions of the game. I have previously played an online game that was almost flawless so these reports might be inaccurate.
Finger crossed its just the servers warming up before the storm. Otherwise we might have a riot on our hands. Let us know how your online experience is shaping up.
