It's very sad, I love KNC, had an order for Neptune in the first hour or so, but their announcements combined with bitcoin price dropping makes refund the only thing to do. 
The only thing keeping me hanging on to my order is the geek in me wants one of the very first machines delivered, if I had a later order it would have been refunded for sure, but as each day passes I'm getting closer and closer to a refund.
KNC, if you do actually care about your customers
1. Produce some Jupiters very quickly and sell them to existing customers (Ideally your 1-500 customers first !!!).
2. Issue a proper statement about what neptune buyers are going to get and when, not vague comments that tell us nothing
3. Offer us something to make it worthwhile waiting, as I can buy almost 3TH TODAY and have it delivered in a couple of days for the $10k
Number 3 is the killer and is the reason most people are jumping ship, I love KNC and don't want to leave but I need to hear something soon
