While I doubt it....I totally expect Sony to surprise at some point with a major release....be it GOWIII in December, or GT5 early next year...I think they are going to do something like this.
GOWIII (with a marketing campaign fitting it, and LBP, and R2..SONY!! Hello, advertise!) at Xmas would be huge...
