Sony announced yesterday that 80GB PlayStation 3 models bundled with MotorStorm are now available at US online and brick-and-mortar retailers for $599 (about £300). 60GB PS3 models for $499 (£250) are available until supplies last.

Sony said the new machines will "appeal to the online gaming and entertainment enthusiast" looking for additional storage space to download games and additional content such as movie trailers and images from PlayStation Network.

"The 80GB PS3 offers expanded options in the PS3 family of products for those who want to enjoy more downloadable content," said Peter Dille, Sony's senior vice president of marketing.

"The new model will provide ample storage space to meet the appetites of those who wish to download content today, and for many more years to come."

In the same release, Sony claims that unit sales of the recently reduced $499 PS3 have surged 115 percent at the company's top five US retailers. Sony expects 60GB inventory to deplete sometime this autumn.

There's no word yet on when the 80GB PlayStation 3 will be available in the UK, but when it was originally released in South Korea, Sony suggested that the European markets may follow.
