A:AnswerThey DID offer the Nikon 850 as a pre-order, that's when I ordered mine. The 850 is now shipping to all who pre-ordered, (got mine on Monday). Since it is shipping, it is no longer a pre-order item.
A:AnswerThe camera is being sold in the US and BestBuy is an authorized dealer, therefore it will have a USA Warranty. I do not believe BestBuy sells "Grey Market" items..
