Sony announces new smaller and lighter PlayStation 3, arrives September 25th While weâ€™re still waiting word on the PlayStation 4, Sony (SNE) is hoping weâ€™ll make do with another revision of its PlayStation 3 console. The company on Wednesday announced that its new CECH-4000 model, slated for release this fall, will be 20% smaller and 25% lighter than the previous model and will also ditch the slot-loading optical drive in favor of a disc-tray that slides open sideways. The new PS3 will be available in two models: a 250GB that will sell for $269.99 and a 500GB model that will sell for $299.99. The 250GB model, which launches on September 25th, will be sold in a bundle with the game Uncharted 3: Drakeâ€™s Deception and come with a $30 voucher for digital content for the game DUST 514. Shoppers looking for the 500GB PS3 will have to wait until October 30th when itâ€™s available as a bundle with Assassinâ€™s Creed III. Of course, users will still be able to replace the default hard drive with their own 2.5-inch drive. Sonyâ€™s new PS3 fits comfortably with its 10-year console strategy and follows the companyâ€™s tradition of reducing the volume of its consoles as the years go on (a move weâ€™ve seen Sony pull off with the PlayStation 2 a number of times).
