i think it can reach 10 million lifetime. the last one probably reached 8-9 million. we know that UC1/2/3 sold 21 million. so UC4 reaching 10 million isnt that far out of reach, specially if its good, and if it has the biggest opening.
though not releasing in the holiday period, unlike any other of the previous 3 games, might damage its chances to reach that milestone. i think Sony are expecting roughly 8 million for the game.
