Well,the Original Avalon unit consumed 600+ watts @ 60-70GH.What BKKcoins is designing MAY use 32 watts per 5GH board.
So,BFL's 5GH unit consumes 27 watts.
The difference between 27 watts & 32 watts is not enough for anyone to really make the Klondike Avalon be "unprofitable" anytime sooner than BFL's units.
That argument is null & void
Yup. What's going to happen is the next gen asics will arrive (in the next 3-6 months) that will make all the current gen asics unprofitable.
Sounds like a variation on the same line (some) current miners have been FUDding new miners with all along so they can keep their share bigger.
