In a statement today on Konami’s Japanese website, Konami apparently denied the exclusivity of their Pro Evolution Soccer 6 release, declaring:

It has been falsely reported on some websites that KONAMI will release its “Pro Evolution Soccer 6” exclusively for Microsoft’s Xbox 360. These reports are not true. KONAMI is currently proceeding with the production of a multi-platform release of “Pro Evolution Soccer 6” so that as many people as possible can enjoy the game.

Gamespot has dug into the statement a little further, but this has only muddied the waters. The actual text of the statement would seem to be refuting any websites that claim that the game will be exclusive to the Xbox 360, and not “next generation” exclusivity as claimed by Microsoft. However, Gamespot’s source at Konami indicated that the release was aimed at Microsoft’s release specifically. This whole thing very well could come down to a semantic issue, where the marketing-speak that Microsoft chose for their press release conflicted with Konami’s understanding, and should be clarified soon.

Update: 1up was able to talk to the series creator, Shingo Takatsuka, and he stated that the exclusivity window would be through the end of the year only, and that a PS3 version of the game was already in development.
