It ain't going to cost anywhere near $100k. I'd say C6 Z06 money tops. Yeah sure they're testing it out with a 997 turbo in tow. Total marketing ploy. Despite the camouflage on the GT-R, Nissan KNOW if they take the car out for a spin on the Nurburgring the spy photogs will catch it.
Oh and as usual..."Skyline" is an overall lineup of sedans and coupes of which the GT-R was formerly the big bad mama range-topping model. The regular Skyline is the exact same thing as an Infiniti G35. Unless something out of Nissan has changed, this new car will just be the GT-R since it's not a variant of the existing or soon-to-be-released Skyline coupe. Everyone over here who plays Gran Turismo got the word "Skyline" associated with the GT-R in their head and is still applying it to this new GT-R. But you knew that.
