Sony Europe speaker James Armstrong expects Gran Turismo 5 to be out by next Christmas.
Armstrong's comments fall in line with Sony US chatter from March, when we heard that Gran Turismo 5 was "about a year away".
Most recently, Polyphony Digital boss Kazunori Yamauchi said both Gran Turismo 5 and Gran Turismo PSP were "moving forward", although he couldn't mention any specific plans.
He could, however, tell us that Gran Turismo 5 cars had reached a "target level" of detail, and that work would now spread to environments and crowds.
Yamauchi has said roughly 150 people have so far worked on Gran Turismo 5 for four years, and that the fifth game has cost 50 times that of the 1997 PSone original.
Gran Turismo 5 Prologue, a precursor to Gran Turismo 5, was released back in March, and features some of the shiniest - if indestructible - cars ever in a videogame.
