that skyline is so far off that I would highly doubt if it was close to the concept you see before you.
also, its gonna be a wait and see thing with the new skyline. past generations were considered incredibly good cars stock, and with a tuner's assistance, you could easily triple the stock HP on a stock block motor.
unless nissan pulls together some good reasoning, it may be nothing more than a magazine cover car for a while...and may never have the accolades that the past generations have rightfully earned.
