Given that the new Finfet node is considerably more expensive, there's no doubt they'll mostly harp about the power efficiency and size. Extra transistors won't be free though, so high end is going to be very expensive, and most likely they'll seriously cut the chip sizes. You can't seriously expect AMD or Nvidia to just make a 600 mm^2 chip right out of the gate. This will no doubt disappoint people who are expecting a new Titan by next summer. More than likely all we get to see this year is a mid-range flagship like the 980 that they'll try to sell for $600.
