You needn't rush though as they'll stay wrapped until January 21st. For now it appears this holiday treat is for Japan only, but hopefully it will go global.
The cars are a Lamborghini Murcielago LP 640, a BMW M3 Coupe and a Jaguar XJ13. These speed machines are in fact already available with the Lamborghini and BMW part of the Collector's Edition and the Jaguar a promo from the GT5 Facebook app.
Let hope Sony will share this "Christmas present for Gran Turismo 5 fans" around the world and not keep it just for the Japanese PlayStation Store.
