Ok, I did not really feel like joining yet another "VGT hate" discussion, but now I really must express my own thoughts regarding all this;
This whole project, the Vision GT project, was never meant to act as the main and sole vessel of new cars for Gran Turismo 6, in my honest opinion. However, it was PD's treatment of it which caused the project to do just that, and that is the key issue here. These cars are not real vehicles; they are half concept cars, half marketing tools, for both Gran Turismo and the brands who are a part of the VGT world. Are they meaningless in most single-player races and online lobbies thanks to oversized PP ratings and over-the-top perfomance? Yes, they are, I am not going to act in denial towards that. But they exist, for the better or the worst, and PD will not halt such a large project now simply because people have split opinions towards the cars themselves. They are, and should be advertised as, a side attraction to the main picture that is GT6 itself.
And yes, it does sound cliché at this point, but all this hatred towards VGTs is solely PD's fault. Imagine if you got a real-life, brand new production car alongside each VGT release. Yes, you would still have 18 or so "meaningless" VGT cars, but you would also have 18 or so brand new, real-life production cars which would probably suit the desires of many eager fans. Say for example that Ford brought out the new GT alongside their VGT car, at the time of the VGT's release... It wouldn't be so irrelevant now, would it? Fans would get the new GT to drive in the game, alongside an exclusive concept car which was custom-made for the game itself. Of course, this is not happening currently, and with the current drought in production car DLC for GT6, the VGTs have to take the full brunt of people's negative feelings towards said drought.
All this blind hate towards VGTs won't matter in the grand scheme of things. PD will not simply cut ties with the remaining manufacturers, unless the manufacturers themselves do such first (i.e. Alfa Romeo and Bertone). Do I admire the thought which goes in each VGT car? I do, but I will not dismiss the bigger problem. PD may or may not be busy with future GT installments, but they need to provide GT6 with a bigger influx of real-life production cars. So, in short, I'll take the VGT... but it should not come alone, but rather with a fellow non-concept, a car which exists in real-life and can be bought from a dealership.
