I hope they don't go for to much perfection with the Neptunes... This still is an arms race and difficulty
rising exponentially is still a big part of mining. no..?
bottleneck with controller boards 
that's the simplest component of the whole miner. Could you
please explain Orama..? I'm not sure I'm believing this unless you/KNC can explain with more detail. KNC have
pulled miracles in the past with bigger volumes and now there's a bottleneck. I'm sure another PCB
manufacturers that can make it happen if existing manufacturer is busy.
Also. didn't KNC tell us to keep BTC handy for these Jupiters. What's changed..? Fear of Neptune refunds..?
by the way they sold out this shouldn't be the case.
Come on, we're all men here.. spill the beans even if some will get upset I'm sure we'll get over it.
I'm guessing the BBB (BeagleBoneBlack) could be a bottleneck.
Cointerra is using them too, and probably many others, because of the 'powerfulness' of a BBB compared to a raspberryPi.
BeagleBone is a US (non-profit)company/foundation, and rPi is from the UK:
Hopefully Cointerra (US company) didn't sign an exclusive deal with BBB, for a certain amount of time/products.
