20nm will never be developed by KNC.
Why? Because if KNC never has to deliver a working Neptune to your door (c'mon aren't we all thinking we'll never see a real Neptune in person, right?) Then what incentive do they have to build the new product when the 28nm Jupiters will do the hosted mining job perfectly fine with ultra cheap electricity.
We might see photos of datacenters filled with "our" Neptunes hashing away. Shh, they'll just be Super-Jupiters in newly designed boxes. But we will never have direct control of our individual boxes, just some vague, generic hashrate that we may have minimal control over. So we'll never no for sure what KNC is hashing with.

Why will no one see a working Neptune? I will be having mine delivered, regardless of the data centre.
I can almost guarantee that we will ultimately never be given the option of delivery for whatever bullshit reason they conjure up.
How much do you want to bet?
