According to an article in Car & Driver, this version of GT is far from release. The story illustrated the problems with creating a "game" this deep. The challenges are unbelievable, as you might imagine.
I'm currently running a PC based simulator called GTR 2 complete with racing seat & Logitech pedals & wheel. It's possibly the most realistic sim I've ever owned .. but not as much fun as Gran Turismo.
But it will fill the gap between GT4 and GTHD.
