Don't hold your breath. It's actually already right there for the IBM alliance: SOI. More specifically FDSOI (fully-depleted SOI). They've been using this technology since the 90nm node. Intel has been avoiding SOI since that time, and trying to find every technology that give it the equivalent featureset as SOI without having to use SOI. They came up with HKMG as the big marketing announcement in the last node, and now FinFETs. FinFETs increase the gate-source capacitance in exchange for higher drive current. It's not going to have nearly the same level of advantage as HKMG gave them, and HKMG really didn't give them all that much of an advantage in power-savings or performance during the last node either, despite all of their hype for that technology too. As I said, these technology announcements are for the sake of the announcement, nothing else. Yousuf Khan
