There is nothing exiting these days. I miss the days with updates from burnin and KnC, but i still have faith! Waiting for the 5TH monster at 2kW 
I think the opposite: i think that at some point KnC decided to go with 28nm instead of developing 20nm Neptune (at least on time-perhaps they will do it in Q3-Q4).
That's why they are maintaining almost complete radio silence, hoping that this tactics will reduce refunds and they might be successful at accomplishing this.
Instead of developing Neptunes, I think that they are using our funds for datorhall build-out, while using cash generated by the datorhall to fund slowly trickling refunds. In addition, they re-instituted batch 2 which behaves similarly to an equilibrium in a chemical reaction, with all going back and forth on numbers, suggesting that both refunds and new purchases are basically in balance.
In fact, i think that as long as refunds can be covered with the datorhall revenue, they do not care if eventually everybody refunds.
They will have a brand new data center and NO OBLIGATIONS. Sad, but most likely true.
I suspect that is what Knc is doing, but surely they can be sued for fraud. If they have no intentions on delivering what they already sold and are misusing customer funds, they should refund all orders immediately.
