IIRC from reading the presser, they've slowed it down for now, a 2-3 year cadence instead of 1-2. From other articles I've read on the web there appear to be several initiatives that Intel and others have been investigating for some years that may be about to bear fruit. Advances in understanding nanotechnology, for instance carbon nanotubes + conductivity, and biotechnology, programmable DNA, are still somewhat futuristic, but remember as well that PCM is about to roll out by several industry leaders including Intel. I wouldn't be surprised it the tick-tock thing will be replaced with a completely different paragdigm shift requiring us to think in terms of the next new bacteria's genome or the next atomic alloy combo.
Interesting times my friend.
