Sony has sent word of their new offerings for the US PlayStation Network today. Most importantly for racing fans, Gran Turismo HD Concept will be upgraded for free to version 1.2, which enables force feedback through Logitech steering wheel peripherals. (European gamers have been enjoying GTHD 1.2 since the console's launch in the region.)

The Grand Theft Auto IV trailer is also available for download in high definition, as is the Armored Core 4 demo. Microsoft's Peter Moore, proud that Xbox Live got the GTAIV trailer up before Sony, has added yet another tattoo on his arm to add to his collection of AAA-titled inkings.

All of the content will be available free of charge and should be online sometime today.

[Update: It's the Armored Core 4 demo, not trailer, that is released today. All parties responsible for the error have been thoroughly sacked.]
