Read about it here: Next Gen GT-R Coming in 2018

For a moment there, there was some uncertainty that the GT-R would see another iteration. Now though, we know that a completely new model is due to arrive in 2018. We'll also be seeing an update next year. It'll likely be a facelift similar to what the R8 just got.

 

I think the only people that were uncertain about the rumors about the GT-R being discontinued, are the very people that published this article that they are no longer true... I think the rest of us were pretty sure about this information already.

The only relevant topic yet to be determined is the power plant.
