S2 upgrade is coming, but until the hardwares are mass produced in the assembly and tested for specs for each item, we can't say what the spec is...
But it should be less than 0.4w/GH. (ants on the engineers floor tells me it would be in 0.3x in range)
PSU upgrade should not be needed. Existing 1000W PSU will be more than sufficient.
If there is a clear need of spare parts, then it will help us determine what we need to prepare!

** Aaaand.... Please remember,
ANTS are always in-stock sale, not future unknown shipping date when it is announced for sale.
HASH NOW is more important than waiting for weeks/months for 0.2Xw/gh miners that may come out in a few months.
thanks for the update Bitmain, my own thoughts follow:
1) sounds like it will achieve ~2.5TH using the 1050W PSU, assuming your <0.4w/GH is at chip level, and not at the wall. I assume each hashing board would thus contain 16-18 BM1384 chips to achieve 250GH/90W.
2) sounds like doing this could provide some room to overclock the frequency if using a 1200W PSU (maybe 2.8-3.2TH) depending how many chips and what voltage is used
3) the only ANTS currently in stock are 0.8w/GH C1 units at >1BTC/TH not counting power supply and cooling kit. IMO thats a bit high.
3b) I emailed yoshi a few days back and the S2 upgrades were predicted for late march, and very little info was available about the S5 or any further units. I want to add 10TH+ of hardware to my collection this week, but the C1 is perhaps the least interesting option available. With the S2 upgrade path, will an S6 be available?
I would like to see bitmain produce 4 things:
a) S2 upgrade kit, consisting of 10 hashing boards that directly drop into a S2. hopefully 0.7-0.9 BTC/TH considering the small weight and minimal # of components
b)
an S6, either built like the S2/upgrade-kit, or built similarly to an S4 but using S5 boards. At this point in the mining 'game' it doesnt make sense to run dozens of 1TH units, each with thier own control board and case. combining 3-10TH into a single unit would be cost-effective for customers who mine in dedicated locations
c) an barebones S6 kit without PSU, fans, or case. I have a lot of fans, PSUs, and shelf space to run a barebones unit if the small size/weight means a significant price discount
d) more
S5 units
