You are all part of the marketing! 
First you need to stop thinking of GT as just a game, this is one of very few games that go far beyond the gaming market, might even be the only one, then you realise the sheer power of the GT brand and the amount of cross promotion that is going on is just nuts.
I´ve been in a couple of sonys viral marketing experiments and i wouldn´t put it past them to use it to start the marketing as it´s one of the most effective ways to build the hype, get the diehards excited as soon as they are in full gear and the buzz is on they will start the tv spots magazine ads and so on where the date gets known from there they ramp it up even more.
Those thinking any other game would affect GT is in my opinion quite wrong as none of them can compete, hell GT5P sold more than alot of games do and that was just a glorified and early taste demo of what is to come.
But we will see soon enough tho.
