Gran Turismo HD, which would have only featured a few maps and cars and make the rest availiable for online purchase, has been canceled. The reason to this is, that if you wanted to purchase all maps and cars, it would have cost you hundreds of dollars. GT HD won’t disappear for good though. Gran Turismo HD Concept will be a free downloadable (in Japan) starting on December 24. Polyphony Digital is now concentrating on Gran Turismo 5 for the PS3.
