I too am frustrated by not right now having new KnC gear hashing. Thing is I look at my Neptune pre-order and look at the present relative superiority of Jupiters over the competition and the Jupiter profitability track record, and I expect the Neptune will have a similar relationship to the competition when it fields.
That's not to say all of us might not get screwed, KnC machine owners somewhat less than others. Screwed if dark horse mining farms get super cheap gear of their own manufacture in an overwhelming way.
So, what would be the alternative? Leave mining and buy btc for its appreciation? We know the banks aren't going to quit scamming the general public with currency expansion. We know peace isn't going to reign on into the far foreseeable future, Syria and the Sudan not withstanding, and that would mean money movement into Bitcoin. Some questions are: a) how long do we have to wait for KnC gear, b) will all the KnC gear made available be sold to pre-existing customers or will the numbers of miners be such that it will be open to the general public. Like those dark horse mining farms turning their btc into Neptune purchases, c) how bad will the network hashrate get and how soon?
Sorry but KNC miners gear is vastly inefficient compared to some other devices out there. A good 28nm chip design should take anywhere from 1-2 years not 7-8 months. But as Bitcointalk is mostly a marketing forum the idea of having the first 28nm is was better than actually having an efficient well designed machine.
Also, I very much doubt KNC will be hosting in the future as there previous design in terms of thermodynamics etc. was woefully lacking, thats why there were delays for the hosted miners.
