Final Fantasy XIII is a SYSTEM SELLER, and the 245k PS sold had little to do with Holiday Boost. In case people are forgetting when Advent Children Complete got out with the FF XIII demo, PS3 sales in Japan saw a 288% boost sale in Japan (16.7k the week before the Demo got released and 62.5k the week the demo got released) And that was no PS3 slim. Same thing happen again: 75k the week before the game releases and 245k the week the game releases.
