Further improvements still needed
If you're playing Pro Evolution Soccer 2008 on the Xbox 360 or PlayStation 3, you may have noticed an update is now available. This free download has been issued to address online lag as well as slowdown that affects the game in both online and offline modes on both consoles.
The PlayStation 3 update also fixes problems associated with downloading the game to the console’s hard drive.
PES 2008 has been under close scrutiny from both fans of the series and media alike. Suffering from various glitches, it hasn't provided the smooth gameplay mechanics we have come to expect from the series. Indeed, the initial reaction to these updates aren't what Konami would have hoped. In various forums, gamers are reporting continued lag and slowdown.
Though Konami claim they are "still working on improvements", they'll be regretting not adding a final few layers of polish to their title as many fans have already decided to get their kicks in rival's FIFA 08 instead.
