i am also one of them. i bought a logitech wheel set-up and GT5 Prologue just to use on my old flatmates PS3. He moved out and took the console and his massive Sony Bravia flat-screen with him :'(. Still, i'd gone as far as i could with GT5-P. Waiting waiting...
i tried one of the Samsung TV's yesterday with a 3D blue-ray DVD, and i reckon it's gunna make the full version of GT something pretty damned special having a 3D mode, maybe even as close to real driving as possible without having one of those enclosed g-force simulator rigs. no reason to assume it won't be crystal clear (comparing it to a 20+ year old game used with red/blue glasses is a bit retarded).
not too keen on paying full price for a 3D TV when GT5 comes out, but with any luck there'll be some bargains to be had by then.
