Because, frankly, the Sony PR team are, in a word s**t. They never look more than 3 weeks into the future.
Sony are going to want to completly sell out the 60gb this side of Christmas. After that they've basically got to release the 80gb. One would assume that this has a smaller CPU and GPU. They also need to new SKU release to bundle the Dualshock 3 with.
Besides, it's not the first time Sony have shot themselves in the foot.
