Sony’s grand plans for a two-part GT HD, featuring downloadable, hi-def GT4 content on the one hand and an authentic GT5 taster on the other, has bitten the dust. What started as "Vision GT" - a quick ‘n’ dirty demo designed to show off the future - has, via GT HD, become GT HD Concept. Available only as a free 630Mb download from the PlayStation Store, it’s a small, but free, look at how GT looks in glorious high 1080p definition-o-vision. And it’s free. So you can’t really complain. Or can you?
