I guess interest in the Klondike will spike again once the asics are actually shipping at a fraction of the current costs.
There is still significant cost in the rest of the components and assembly. Best to apply the design to new chips if possible.
After all the dust settles from the group order refunds Avalon will have a lot of inventory on hand for immediate delivery. Keep in mind Avalon paid the foundry considerably less to produce the chips than they were selling them for. I believe they'll be able to discount in-hand chips to the point where it'll still be profitable to manufacture them into boards.
My vote is to keep going on the Klondike project to get the current k16 boards hashing, and prepare for any design modifications needed for the Gen 2 chips.
