I wouldn't rule that out with that Intel "3D transistor" thingie. Power dissipation goes down, clock can go up. And the device also gets smaller, so more cores can be put on the same chip.
Not only that, but we are only starting to play with memristors. Silicon still has some mileage.
I would rule it out. The 3D transistor design buys us just a few percent but really, we're starting to hit the walls of physics with our current technology.

Will 10Ghz be possible in 2020?

IBM already has 5 GHz chips. Do they know some physics Intel doesn't?
Not really. They do have some cool fabrication tech though. They also run a different ISA and different pipeline which can make a world of difference.
Really though, I wouldn't expect them to hit 10GHz anytime in the foreseeable future.
Don't their chips use lower voltages? i.e., lower heat, but less distance within the circuit path that a given cycle can take.
