I was at my local dealer today, and asked about pricing and dates for the 1DX. He said orders were placed about a week ago, but could not give a availability date or price. No word of 5D MK III either, except lots of photographers are asking him. They have also placed their orders for D4's, but no firm release date yet.
They do a lot of sales thru their online store, www.onecall.com
, but its nice to be able to demo before you buy.
