The three-wheeled one? As far as I'm aware, that car (well, thing) *cannot* complete a lap of the 'Ring. I think the four-wheeled one can, but only just.
Considering all the GT5P cars have interior models, i think its pretty safe to say thats mis-quoted or been mis-translated for him.
They've said for a long time now that there will be 170 cars fully modelled with damage, and ~800 with interiors but no deformation damage, only scratches and mechanical failures.
I'd take it with a pinch of salt until its said in an official statement which has been prepared and double checked, rather than an impromptu comment.
Considering the comment was almost certainly taken from his UK trip to see the GT school folks and nothing else has come from things he's said, this wasnt a planned announcement or update, he's just answered questions with answers we already know but people still insist on asking cos they're morons who think if they ask when it'll be released they'll be the first he tells, as if nobody had thought to ask him and thats the only reason its not on shelves.
I can live without it, but im not buying into it. We've also heard that GT5 will have a track editor, that it'll be a launch day title amongst a dozen other dates, we've had legit PD screenshots with bikes in it, official sony mags stating that Indycar would be in there.... tons of things, none made as official statements by PD (except one Asian launch date) only tidbits of info thrown around, and misquoted or misunderstood like chinese whispers.
Until they make an official statement, then i'll take it with a pinch of salt.
Aww man. The premium models are probably Race cars, rally cars, new supercars (e.g. SLS AMG and 458 Italia) and possibly tuned cars. I wouldn't be suprised if that statement is true. It would take forever to accurately model 1000 cars for such a game.
