B&H has instant discounts and is offering both bodies for $1299.00 and $1499.00. Their site shows they will honor this pricing for backorder with expected delivery in 2-4 wks. Many Ebayer's are asking more than this for their pre-owned bodies. Don't know how long this will last. Could not find similar pricing when I looked on Adorama's website. Here's the B&H link.
