The current Nikon 200-400mm f/4G ED VR II model
The Japanese price of the upcoming Nikon AF-S NIKKOR 180-400mm f/4E TC 1.4 FL ED VR lens is going to be ￥1,287,900 including tax, or around $11,400. Based on this information, I am guessing that the US price of the lens will be around $10,000.
The new lens is expected to start shipping on March 9th, 2018. The official announcement should be on Monday or Tuesday.
There is also a new Nikon EH-6c AC adapter for D4, D4s and D5 DSLR cameras.
