These references can be called anything, but there is a material truth. The truth is that this supposedly dated list pointed Watkins Glen, Road Atlanta, Grand Valley, High Speed Ring, Deep Forest and Trial Mountain for the possible future of the franchise, and all of this was confirmed in GT7, fitting like a glove.
I don't know what the nature of this list is, but predicting Road Atlanta and Watkins Glen and confirming them in the first year of GT7 is evidence that this list is reliable.
It's no exaggeration to say that just as new Nurb layouts may appear, Red Rock Valley and Cape Ring may also return. After all, the circuits are on the list that is proving to be credible.
