It's true. According to CNN, Sony reduced the MSRP of the 20-gig PS3 (that's the lower-quality version) by 12,200 yen, or around $105. Sony is going to allow retailers to price the 60-gig version of the system themselves, using the MSRP of the 20-gig version as sort of a starting point.
However, as far as we know, this price drop applies only to Japan, whose original price of the 20-gig PS3 was approximately $515 (now it's closer to $410). There is no word on any price drops anywhere else in the world as of yet, however, and we can only hope that Sony will also make a similar announcement applying to the North American and European releases of the PS3.
