Demo Gran Turismo HD by Bhavin Shah Gran Turismo HD, in its expected form, has been cancelled. Sony has announced that the next milestone title in the GT series will be Gran Turismo 5. Earlier this year it was revealed that GT HD would be released with minimal content at a low price, with cars, tracks and other add ons available as (paid-for) downloads. Sony and Polyphony Digital has ended the experiment prematurely. However, it was also announced that the game would be repackaged as a demo, to be released in Japan on December 24th via PlayStation Store. The demo will be titled 'Gran Turismo HD Concept' and will be available free of charge. It will include ten cars and two layouts of a single track. There is a chance that more Concept downloads will be released before GT5's expected release in 2008.
