As has been well documented, the official Playstation Blog is already on record saying, "we can confirm that Gran Turismo 5 will not be available this November 2nd, but the game's release will be coming this holiday season."
So what gives? It's pretty simple. Retailers' national print ads like these are finalized weeks or even months in advance (you can expect the big Black Friday circulars to start leaking any day now). This is likely just a case of the stores getting burned by Sony's most recent late-in-the-game GT5 postponement after the weekly sale flyers had already been approved and gone to print.
if you take a look at the Target ad, it includes something very important: an asterisk with the warning, "release date subject to change." Prescient, given Sony's history GT5 "release dates." So, despite what you may see in your Sunday paper's ad inserts, don't plan on picking up GT5 this Tuesday. The wait continues...
