Looks official!
From their update:
Avalon Generation Two Chips 55nm
Those who have invested in time and money on Avalon Generation One based devices and clones can rejoice in the fact we had the foresight to make Avalon Generation Two chips completely backward compatible in every way with 110nm generation one chips, which can be expect to go on sale Late October 2013 for immediate shipping. Avalon will no longer participate in any kind of pre-ordering.
So let the speculation begin!
$/gh/s?
Chips only?
Miners only?
Chips and miners?
Batches, what size?
Just about anything else you care to speculate on.
That last statement brings a smile to my face.
