You know I think it will be delayed for this exact reason.
Logic tells me that with it now being January, the game has a good chance of releasing in the Summer.
But this game continues to defy logic.
A holiday release combined with massive advertising and a new Sony 1st party driving wheel/ GT Sku of the PS3 would do wonders for the PS3.
This gives them time to fully implement the head tracking/PS motion and Full 3D implementation with their flagship title.
Sony may even think of this game as the "launch" for Sony's 3D tech. The game could see a possible bundling with 3D glasses.
Sony knows this, and imo they won't let the opportunity pass them by
Natal... What?
