The KNC hardware is just promises. In the meantime, a Chinese manufacturer can appear out of nowhere with similar specs but available right now.
What if KNC is 6 or 10 months late ? This happen all the time.
We better look for other manufacturers.
Also GPU mining will remain profitable with other algo than scrypt.
The hyper centralisation of Litecoin mining could put down its value to near zero.
I doubt that there is possible that KnC will miss there deadline by 6-10 months, they were a couple of days late on there first Jupiter/Saturn line of bitcoin ASICs and maby they will be month late on there Neptune line but they will compensate buyers with the mining income for that time from there farm in northern Sweden instead so for the buyer of Neptunes a possible delay wont mean any loss.
The reason they just say Q2-Q3 is most likely that there not 100% sure they can have it on the market before 1 july but they think it's possible and surely they wouldn't be more than 3 months after that date(and still within there timeframe, it's not BFL or Hashfast were talking about here..) to market with it, second half of Q3 is most likely the latest it can possibly be if everything in the process takes longer time than anticipated.
Just mention it as i think it would be a good complement to coinfarms current rather heavy weigh on btcminer that will decrease it's return faster over time than litecoin or other scrypt coin mining.
Gridseed may be coming with better priced hardware soon thou(thats way more likely that other competitors matching the specs of Knc soon) with more chips per unit, but probably not down on Knc's pricelevel/MH and the power consumption would probably just be marginally better on bigger units than there 5chip unit and the question there would be if they would mine in what the difference in price is in the time until KnC's miners arrives. If Gridseed would cut there price today down to 50 usd(under 1/3 of there list price of 158 usd) per 350kh miner for example, with 3.7% difficulty increase it would mean they make there price back by 4 sept 2014 and if they would make such reduction in price then we surely should go for such units instead for the scrypt mining, but until the price goes down to such levels KnCminers scryptasics is still an interesting option for the scrypt mining in the future i think.
