This topic has been beaten up and down to death and we will most likely never know what car it will be until it actually comes out.
If Nissan keeps the Primera/G20 connection, then yes it will be the P12, or possibly the restyled european P11 (P11 144 series)
However, I have not heard any rumors of the P12 coming here. Nissan/Infiniti, as well as dealers, salesmen, and the press have all hinted that the car will be rear wheel drive and a little less sluggish. The car will be aimed at competing more with the BMW/Lexus buyers..
Whether the car will be the V35 Skyline (blah, and no this is NOT the Skyline we all love. The Skylines as we know them will know have a new name labeled just "GTR", and this "V35 Skyline" is now a family car.) or the XVL concept (growing on me) will remain a mystery. Until the car is actually on the showroom floor, even what a dealer tells you is all here say.
