2TH for somewhere between (12 x 120v = 1440w) and (12 x 230v = 2760w) is not exactly a huge leap in efficiency.
Slap bang in the middle of that range is 2100w
You can have 2TH with 55nm Bitfury for 2300w
They quoted 0.7w/(GH/s) tho they were very conservative last time with their estimates.
They didn't beat the 55nm Bitfury with the 28nm. Eventually this game will come down to power efficiency.
I don't believe they are using real ASICs but instead FPGA HardCopy ASICs
I believe you would be 100% incorrect then.
If you wanted to undervolt the KnC system it could easily use less power than bitfury and probably have more hashrate per silicon used.
Regardless of the above speculation, KnC uses Standard Cell and not FPGA Hardcopy. This has been said and said and said and apparently still isn't clear enough.

0.7W x 2000GH/s = 1400W
I believe it will be well under that. probably around the 1000W range
No it will be over 1440w because they said US buyers would be down on power and some cores wouldn't come online.
They "Said"
Cole believes that residential power supplies in some households won’t be able to handle it on a single fuse. “American houses don’t have the same supply as Sweden or Germany for example,” he said.
Which has nothing to do with "Cores" coming online or using "more power"
“Maybe a European house can run six chips and a US house less chips,” he said, adding that chips would turn on automatically as more power became available to the box.
