Well, I might make note of something that makes a difference - they say 1Th/s, not 1.5.

Additionally, that 1 Th/s is with multiple chips in a box, and the number is unspecified. My understanding of full-custom ASIC processes is that chips are cheap to make, once the NRE is recovered. Like, REALLY cheap.
So I do believe it is possible, but I also am of the opinion that they are staking an awful lot on the outcome.

The number of chips is not particularly relevant.
What matters is the hashing power to wattage ratio.

Yes, and no wattage has been posted, so right now all we have are guesses.

We have a good guess.  They claim their 3.5 GH/s chip is USB powered.  So there you go.  1400 MH/watt (or better), which means if the 1 TH/s Rig is using the same chips in parallel, 714 watts.  And thats assuming they are using the exact same components in each product, which makes no sense (why produce special cases when you can just offer bulk discounts).

That's why only an idiot would give them money in advance for a product which has no proof of concept (or even proof of development starting).  Their numbers are pulled out of their ass.
