Sony is introducing new PS3 slim models this month in Japan. The PS3 is going white and getting 2 larger hard-drives.
The new 320GB model, as well as a new 160GB version will replace the normal 120GB model. According to a series of sources the 160GB version will cost 29,980 yen (around $342), while the 320GB model will cost 34,980 yen (around $400).
Sony seems to be a little backwards in the coloring scheme though. While Microsoft and Nintendo started out white and added the black color, Sony is starting out black and adding this white color. It looks really good though!
