Howdydoo and Welcome to AF JS.
Worry not for the picture that carz posted (very nice by the way) is the NISMO mod of the 4dr SKYLINE. There is no word yet or picture of the future GT-R. Yes there are many, many pictures floating around the interenet and in magazines that say they are the "real" photo's, but until we hear from Nissan take them all with a grain of salt.
BTW: more info on the NISMO V35
