Yeah blame Sony when Atari is the original publisher. Atari signed over publishing rights to Sony in Europe for the Sony line of the game, which helps Atari some since now they don't have to pay licensing fees associated with releasing the game in Europe.
It's still funny that they announced this in the final stretch of the games development. It's also really weird to see the game published by two companies one getting an earlier release window.
First time for something like this to happen...
