Konami has just released the unfortunate news that the first demo for PES 2012 has been delayed on the Xbox 360 due to "unforeseen issues." It will now be available for download from the Xbox Live Marketplace at some point during September.
Despite this, Konami has still released the demo on the PlayStation Network and it is also available for those who wish to check out the demo on the PC.
The latest version of PES features many improved mechanics, as one would expect. AI changes related to off the ball incidents while there's also a new teammate control system.
