Batch 8 of the S3 and the S1 upgrade kit do not even resume shipping until September 20th.  so I would not expect to see another device from them anytime soon.

You will be pretty shocked, they might be testing new chip for a s4 right now.

Are they switching to 20nm for S4? Any info when we can expect it at all?
I highly doubt it.  Chances are they're going to follow the same paradigm with the S4 as they did with the S2: lots of underclocked chips.  So, they'll continue to use the BM1382 that's in the S3.  Quite honestly, I'd expect the S4 to look pretty much exactly like the S2, with some minor improvements like better bracing of the hashing boards on the backplane, etc.  My expectation is somewhere around 2.2TH/s at 1300W will be the specs on the unit.

Well whats the point of making new ones at the same W/GH ratio? We can just order bunches S3s.
It's a better W/GH ratio... S3 is 0.77W/GH, my expectation above is about 0.59W/GH.  I don't think they're going to see the kind of improvement they saw on the S1/S2 simply because the BM1382 chip is already achieving a respectable power to hash ratio.  Hopefully I'm wrong and they manage less than 0.5W/GH... but I doubt it.

the S3 is already getting outdated with only 453 GH/s at the price of 0.58 BTC without PSU

Any news on the upcoming Antminer S4 ?

We do need a solid unit producing more than 2 TH/S +,  maybe at the price of 1,5 BTC or lower

I was hoping something like 5-10 TH/s and really compact. Waiting patiently..

they should come out with their S2 upgrade before they announce an S4.  maybe they will announce in conjunction.  if you assume the same ratio increase as the S1 -> S3, then the upgraded S2 "should" be somewhere in the area of 2.4+TH, and i think with some room for overclocking.
