We reported yesterday that the Famitsu was reporting sales for Final Fantasy XII at "1,516,532 copies - the biggest launch of a PS3 game in Japan. The game also helped to ship a tremendous 245,000 PS3s, up 225% from the week prior."

Well now we have the official Media Create numbers which put Final Fantasy XIII sales at 1,501,964 in the 4 day period between the 17th and 20th of December. PS3 sales increased to 237,086 over the course of the full week ending 20th December, which brings LTD sales for PS3 in Japan to 4,276,480 units.

Sales of Final Fantasy XIII are lagging behind other big releases such as FFX and FFXII, but are slightly higher than FFX-2. It is however, important to note that the install base of the PS3 is significantly lower than when those games launched. It will be interesting to see how well the game sells next week, and if it continues to boost PS3 sales.
