Gran Turismo 5 Pushed to November?

Gamervision reports: "Sony’s racing series, Gran Turismo, is one of their biggest names when it comes to exclusive software. Besides being one of the highest selling franchises of all time, it’s also a huge console seller, as was apparent when the developer released a Prologue to their full title to quench the thirst of fans who were eagerly awaiting the 5th installment. As of now, it’s "officially" slated for a Summer 2010 release, but it appears as though that might have changed, and the game may be blowing past that date and skidding to a stop a few months later to expected, sometime in November."
