PES 2013 could release two weeks before FIFA 13, a retail source has suggested to

Speaking to, our source - who has asked to remain anonymous - claimed that the October release window for PES 2013 hinted at by a recent advert was no longer relevant.

Instead, our source claims that the date carried by Blockbuster's website is "more accurate".

Blockbuster currently dates PES 2013 as being due for release on September 14, two weeks before FIFA 13 goes on sale on September 28.

If true, this would be the first time a PES title has gone on sale before FIFA since the launch of Pro Evolution Soccer 3 back in October 2003.

PES typically goes on sale in October following FIFA's late September slot.

Konami's CEO "is personally involved to ensure all licensing is resolved in time for this date," the source added. has contacted Konami for comment.
