Should be roughly 1.38 million for December for the PS3 because Sony wanted to spin ahead of time.
Since Dec 2008 was 726k for the PS3. A 90% increase would be 1.38 million.
No mention of the PSP or PS2 numbers so they must not be great.

Anyone can guess. It takes no effort to throw out lots of predictions and have some of them be correct. You are not and wiser or better for having your guesses be right. Even a blind man can hit the bullseye.
