MGS3's attach rate is 2.9% and MGS4's attach rate is 18.6%. I think attach rate is meaningless. I think Gran Turismo 5 will outsell Halo 3 because Gran Turismo 3 & 4 outsold Halo 1 & 2. I can make other points but this sums things up pretty well. GT is the more popular franchise and the size of the PS3's user base will likely do little to stop GT5, especially if Sony cuts the PS3's price (which is likely considering how far GT5 is from release)
