So... nobody has a clue what's going on?

 Send ioi a PM with information saying that the game has sold more then what it lists on the site.  But you might need to give atleast one more source, is it listed on another site with the same official numbers, does the Insomniac site have them listed with sales?

 I've got no other source for the numbers, and that number is for four combined games - makes it pretty hard to give anything solid on numbers for a single title. I'm just wondering why VG Chartz numbers are off by around a million units per title - assuming the guy from Insomniac isn't making up numbers, which I don't believe is the case.

VG Chartz doesn't even have any real numbers for Deadlocked. It has ~210k for Japanese sales and nothing for American or Other. Assuming that the total for Deadlocked on VG Chartz would be around 2 million (seems in line with the declining sales as more sequels come out - and perhaps even a bit generous), we'd arrive at 9.5 million instead of 13 million.

Ratcher & Clark on PS3 will see sales of 300-350,000 (during it's first year or so) in NA.

Another hyped flop for PS3.

Uncharted perhaps 250,000 copies.

 a) That is not a flop, it would mean that one in 7 PS3 owners in NA own Ratchet and Clank, that's not bad

b) Heavenly Sword has already sold about 210,000 in NA in one month, and will easily be able to get to 300,000 in NA by the end of the year (and I would guess that it would have more than that in Europe, since it is bundled with the console). With the 40GB PS3 coming out only 2 days after the game comes out, Ratchet will easily be able to clear this quickly, and get at least 500,000 copies. Uncharted will probably get around 350,000 as it will only have one month to sell
