Whatever is true, one thing is certain, PD needs proper PR ( who understand English ).
Not knowing what features or cars, tracks, etc. I can handle perfectly well but that one interview by a magazine can cause an aspect more or less expected by most to become uncertain again whether by translation error or a wrong assumption on our part shows they just don't take PR very seriously.
That they don't want to fully show what we can expect is logical and, although maybe frustrating, fully understandable.
What is inexcusable is that they casually throw around conflicting pieces of info they seemingly are willing to share, and just disregard the effect it has.
If this was an old interview I wouldn't worry, but since it appears to be very recent I'm starting to doubt they've changed the initial plan once again.
So either it is tragically true and GT5 isn't in my opinion going to be the game I was expecting or it is just the uptheenth time something is mistranslated, misunderstood or just made up by a magazine.
The first option is the worst one IMHO as it really affects the final game, the other possible options are avoidable by hiring someone to handle PR properly.
