I thought I had heard that BLF-Josh said that anyone who had ordered in the last two weeks would get theirs by July. But now I can't find that quote again.
Sounds like something he'd say, but I think that assertion is highly suspect given how disorganized they appear to be here in mid April. Josh has also suggested that BFL could assemble and ship hundreds of units per day, but that too seems highly unlikely given their track record and small limited facilities.
I've also noted a conspicuously absent lack of information coming from BFL about their future batches of chips, which is troubling given how quickly they'd deplete the supply they have when shipping commences.
