"Famitsu magazine publisher Enterbrain is expecting big things from the PS3 this holiday season in Japan.  Enterbrain president Hirokazu Hamamura told press earlier today that he expected 500,000 PS3s to be sold in December off of the release of Final Fantasy XIII and the reduced price of the PS3 game console. 

Enterbrain is a leading publisher of the game industry sales in Japan, so a prediction like this definitely holds a lot of pull.  500,000 units would be a remarkable upswing for the PS3, marking nearly a 250% increase from December 2008 and increasing the PS3's current userbase roughly 15%.

Enterbrain competitor Media Create has also stated they expect the Japanese PS3 userbase to swell to 5 million before the end of Sony's fiscal year in March, which would represent a doubling of their userbase over the past fiscal year."
