If they don't jump straight to 7nm then next iteration of 10nm may be more impressive.

At 6-8 cores a 10nm with low base clock and decent boost speeds would probably be a decent option provided it doesn't throttle in the thin/light laptops of today.

Consumer is caught between worlds, the old power hungry one, and the new efficient one where long battery life and cool/quiet mobile systems are the norm (at least that's the hope).
