The real question for me is "What is the stocking situation for USA models at other dealers?" As I understand the facts the USA model of the OP's camera was out-of-stock at B&H, so any theoretical price difference between the US and import models would have been irrelevant. And since some DSLRs are being phased out what is the prospect of getting any more USA models?

Typically the B&H warranty mirrors the manufacturer's 1-year warranty (as in this case), and since B&H isn't likely to go anywhere soon, and is sufficiently reputable and financially strong enough to be a trustworthy warrantor, I'd not worry about the difference.

What are B&H's warranty terms?
We cover all manufacturing defects. Duration varies based on the item. Please see the product page and locate the "In the Box" section for duration of coverage. Typically this will match the manufacturer's standard warranty.

So without any real difference in warranty, and since once out-of-warranty the camera can always be sent to B&H for repair, I don't see much reason for a different price. I would note that some retailers, e.g., the infamous Abe's of Maine, offer no warranty at all on import models unless at additional cost.
