The timing is very sad if this is how it played out. Would have been different if people had the s3+ machines for the last 60 days and then the new s4 got announced.
What would you suggest they should have done? People were asking for S4 since June. How would it have been different if S4 was announced after 60 days or whatever, if people paid for S3+ without paying attention to the timelines and the risks?
Besides until we learn the price and specs it's all speculation anyway. S1 and S2 sold by side and I bought both and did very well with both. I bought S3 but not S3+ because math didn't make sense. Let's see the S4 and let's buy ONLY if it makes sense.
it is already clear where S4 has to be to be competitive. If shipping Oct 1, then minimally ~1.8-2TH, 1100W, hopefully 2.1-2.4 TH and 1300W PSU. Price-$1500-1550 (if 1.8-2th) and $1750 if 2.1TH. If shipping postponed to Oct 31 and 2.1-2.4 Th, then price should be ~$1500-1550. ~1.8Th on Oct 31 will have to cost no more than $1250-1275.
You know you can get 5 s3+ for 1450 based on 500 per btc. which is 2.2 th based on 453gh each and 1775 watts. so pay extra for less power but about 475-675 watts less in power consumption sure. Throw that money away.
