In the week of Dec. 14, the PS3 the total sales were 237,086 units, out of which about 92,000 units were a "Final Fantasy XIII" special edition of Sony's PS3, said Media Create. FFXIII launched on Dec. 17 covered the figures in its first four days of sale.

The re-launch gave a new lease of life to the PlayStation 3, which recorded high the sales over the past three months. The FFXIII software got a major success for Square Enix with sales of over
1.5 million copies in its first four days. In addition, as the game is only available for the PS3 in Japan, everyone expecting FFXIII to fetch even high PS3 sales once it is launched everywhere.
