Okay - update.
My OBB order was still "pending fulillment". I contacted Z1 to see the avaliablity of my DNS-1 for my 400. In stock.
So - I canceled the OBB order and placed the Z1 order.
Z1 - saw my order and based on my shipping choice thought "I bet this guy wants this by this weekend, and using what he picked it won't get there till Monday" They contacted me and said "if you use xxx" it will get there on Fri or Sat- it is a couple bucks more - do you want that?
The answer was, of course, yes!
Wow!
