The Sapphire Batch
This is the first batch under production in quantity. Its lead-time is conservatively 15-20 days.
That was posted in the 04-May announcement.
I'm expecting delivery to Arklan sometime during "the week of the 19th", to use BFLspeak, with delivery to me later that week or early the next.
I understand ASICMINER has been pretty good about meeting delivery schedules so far, with their blade sales.
