It was clear that a 250GB Sony PS3 Slim is coming in time for the Holiday shopping season to match the 250GB Xbox 360. Unlike in Europe, Sony is offering the 250GB Sony PS3 Slim outside of a bundle, you can just get the 250GB PS3 straight up, which I prefer anyway.

The new 250GB Sony PS3 Slim is selling for $349.99 and will ship on November 3rd.
To be one of the first to own the 250GB Sony PS3 Slim you should pre-order it now on Amazon.com.

Sony puts a $50 premium on the 250GB PS3 Slim compared to the 120GB Sony PS3 Slim console, which sounds fair. Sony is now all set for the holiday shopping season, besides the high price of the PSP Go, which still needs adjustment downward.
