PES Team Leader Jon Murphy confirmed on Twitter that there'll be no initial Xbox 360 demo for PES 2012.
Sorry to confirm that due to issues on both sides we can’t release the 1st PES2012 demo for 360. We’ve tried hard but have to give up. [...] We – Konami, the PES team and myself – are all really, really sorry. - Jon Murphy, PES Team Leader
Hmm. With Konami locked down towards further details and Murphy keeping schtum, we've dropped Microsoft a line to see if they have any comments to make.
In the meantime, check out our preview here.
