For 'native' S2 0.4 Wt/Gh means that efficiency has improved twice...
Nearly 3 times. The two that I have consume 1100-1200w for just over 1TH, so they're basically 1.1w/GH

Is it really worth the upgrade for 0.4W/Ghash ? Don't we have miners right now at 0.5W ?
It doesn't seem right now like its worth buying any miners or even manufacturing them with what is going on with the BTC price.
Maybe if it was 0.25W/Ghash or so.

If you want to get rid of one of them, I might buy it. Been meaning to track down a stock S2 for the museum (all I have is the kit version). Probably nobody's gonna sell now with the upgrade looming though.
Have you posted pics of the museum anywhere? Where is it, anyway? I'd like to check it out.
EDIT: btw, mind leaving me trust for the cables I bought last week?

S2-replace PCB will be released after Chinese Spring Festival, and it will be serial powered too, and its power consumpiton at wall will be less than 0.4W/G.

That's the only "official" word I've seen so far, but then I wasn't looking very hard.
Ah nice! Guess I'll hang onto these two S2s that I have then.

I did the math, if they get it down to 0.4w/gh then yea it'll be 250gh per blade. so it should just be a firmware upgrade and good to go. but the way they are charging for TH I doubt it will be cheap.
Don't expect anything before the end of vacation.
EDIT 2/12/16:
99.99% sure it's dead. Not a peep from Bitmain in nearly a year.
EDIT 6/15/15:
I'm keeping this thread bumped until Bitmain responds. Surely 4 months is enough time to say something.

Notification for S2 Upgrade Kit - Coupons being issued
To all customers that ordered AntMiner S2s: We analysed the business case for S2 upgrade kits for end users and determined that it would not be worthwhile for either party.
* The S4 runs at 0.69 W/Gh/s power efficiency, which is significantly improved compared with the S2’s 1W/Gh/s. Even though the upgrade kits used the newest BM1382 chips manufactured at 28nm process, it was not a significant leap in power efficiency.
However, the next generation chip is more likely to be worth doing upgrade kits with.
* The S2 is still profitable to run for the next several months with its 1W/Gh/s power efficiency and so now is not a good time to replace them.
Are we going to have an S2 kit released alongside the S6? BITMAIN, can you come tell us what you're up to?

A short good news for the S2 buyer is that we will let the S2 to upgrade to 1.8TH/s or 2TH/s at very low cost which you can only image now in the August or September. It still depends on many factors to let us achieve that and detailed plan needs to be drafted, But we are very confident that we can make it.
