SPOnG's man in Japan has reported back on Sony's upcoming (if you don't live in the land of the rising sun) racing taster - Gran Turismo 5 Prologue. You'll find the full review of the Japanese version up later this very Christmas Eve-ter-noon.

One area he touches on is the long-awaited return of Rumble as DualShock 3, telling us, "...the rumble-free Gran Turismo HD Concept demo can now be forgotten about. Playing GT without some kind of force feedback is like driving an auto – it’s morally wrong."

Music to our Europe-bound staffers' ears indeed. Japanese gamers will get their first taste of the game's online features tomorrow. We'll turn you back over to SPOnG san for the info: "The online features of the game are due to arrive via a PSN update on Christmas Day, which is impeccable timing. There will be 16-player online races which, assuming there’s no major lag, could potentially reinvent Gran Turismo and begin to shift the series’ focus away from the depth of its single-player game."
