We got ours down here (Australia) a few weeks ago now.
Supply is limited and demand high and the vignetting problem is also probably holding things up a bit while the first few batches are re-aligned and then the later ones checked.
My local guy had mine FedEx'd from Sony after they got through QC. Have no idea about B&H but I do know that suppliers are extremely limited in what their getting. I'd be worried that how many preorders B&H already have if theyre only getting a couple at a time. If you want send me an email and I'll give you my places info, not sure if they have another or can get another but they were awesome while I was waiting for mine, even had me talk with their Sony rep about the delays.
I suspect that it may be a while before supply catches up with demand. As someone else here on the forum said, the EX1 is the Holy Grail of camcorders. I'm trying to buy one before I start a big shoot on January 26th. I'm not holding out much hope for that.
