Ozymadias estimated sample chip delivery between 11th October and 18th October.
By your own supposition you had conservatively estimated sample chip delivery as being 31st October. There are only 20 days between these three estimates.
We know that Ken informed us that we were hashing with 'other resources' on 30th October.
If the 'other resources' Ken mentioned were indeed the eASIC sample chips then the range of 11th October - 31st October fits very well indeed if we just bring your estimation forward a few days.
If they were not sample chips then whatever chips they were would have arrived coincidentally, within that same twenty day window.
My hopes are up!
EDIT: If this is not the case, then looking back at our timeline, the only solid information we have is from 4th September which was the eASIC press release. In which case ANYTHING is a possibility.
My problem with this is the announced delay... for "intellihash" whatever sorcery that is.
