A game doesn't need 1 million copies to be a Greatest Hit.
For PS2 it is the requirement of being out on the market for at least 9 months, and sold more than 400,000 copies (I'm guessing NA alone).
With PSP Sony ditched the requirements and usually just use higher sellers or games they think deserve the push. Same with Platinum.
PS3 might use PS2 requirements, or none at all. I imagine all the games they use will meet those requirements anyway.
