Sony has announced it will be discontinuing its 20GB and 60GB model PS3s in Japan after a final shipment in January, so that they can focus their efforts on the 40GB version.
The decision is in line with comments made earlier this week, Kaz Hirai who said that Sony wanted to get on the "positive side" of the financial equation "as quickly as possible." The 40GB model has fewer components (and features) than the 20 and 60GB versions, and is therefore less expensive to make.
In addition to focusing their attention on the 40GB model, Sony will "vigorously promote the expansion of the PS3 platform" throughout the coming year with"increased efforts to improve software development environment and the availability of a more extensive line-up of software titles for PS3."
