Ok, first of all, Jesus Christ on a bycicle did those pictures came out of nowhere. Secondly, a quick history lesson about Bertone's "death":
Yes, the original Bertone went belly up following a economical crisis that they never quite survived. However, the license rights of the brand were then lent to a new company: Bertone Design, a company established in Milan that is led by architect Aldo Cingolani. We don't know if this "New Bertone" is indeed the responsible for this VGT car, but chances are that it is just the case.
Now, for me, this has been a car that has intrigued me ever since the very first VGT trailer. A car that looked so Wipeout that Wipeout itself looked normal. A car without compromises, no limits, a true concept in all the senses of the term. If these images are real, if this car will indeed appear in GT6, then all I have to say is: it deserves a medal. For being out there, for being itself.
And, most important of all, for being a Bertone when I thought I'd never see the name in a car ever again. Congratulations Italy, you truly hold a special place in automotive design history with concepts such as these...
Early edit: Now, a few extra tidbits: While CarDesignRessource states that "we will probably never see this Vision GT coming in game", I have my doubts. A: If the car is dead, why are the sketches labeled with the year "2015"? If my memory serves me, Bertone died last year, so these sketches should be labeled "2014" for this to make sense.
B: Bertone Design is currently the rights holder of the Bertone brand, and they have two branches. Where is one of them located?
Tokyo. Where is PD located? Exactly... As for the name Giulio Partisani, he is definitely a car designer, with ties to old Bertone. Not to mention that he is currently a Concept Car Design consultant, as his LinkedIn page states. This plot is very thick, if you ask me...
