While estimates from various sources have slated Uncharted 2 as a million seller for some time now, official word comes from Sony(via Geoff Keighley) that the latest entry into Naughty Dog's Indy-meets-Gears love child has cracked a million sold worldwide. 

EEDAR and other analysts predict that Uncharted 2 will top American sales charts for the month of October, selling over 600,000 copies in the US alone.  Media Create has also tracked the Japanese sales of the title to be close to 100,000.

Naughty Dog previously stated they hoped that Uncharted 2 would sell around 2.5 million copies and expand on the the fan base set by the original title.  It looks like they are easily on their way to doing just that.
