Now that we've kind of gone over why Nurburgring Nords. is a great track, here's my contribution. What does the inclusion of this track do for GT4? Does it give people a chance to race an equally-historic track as Le Mans, or does it mean that we get a track that will keep us busy all the way through, or what?
By the way, we DO get Sears Point, and that track keeps you busy almost all the time. And wasn't it Fuji that was called the "Mini Nurburgring?" This track probably isn't going to be in GT4, but I remembered when the JGTC raced the Autopolis Circuit in Oita, Japan. It was Michael Krumm or someone who said the track was a Japanese Nurburgring. Thing is, the track was supposed to have been the Monaco of Japan- a rich circuit prospective to hold a Formula One race, but never happened and went bankrupt pretty quick. I hope the track can maybe get remodeled with all the amenities and such in real life, then it might be a nice track to look into for the next GT. If the Shanghai Circuit isn't included in GT4, it would be a nice consideration for GT5.
If you know your tracks, why not think about what would be cool for Gran Turismo, if not this upcoming one?
