Let me just say that at this point I've never been more unexcited about a D820, D900 or whatever. I love my D810 sooooo much, I'll be a real happy camper for a long time. My old faithful D300 was getting very long in the tooth so I was excited about the "D400". I have my D500(s) now and love them dearly.
Edit: Thx to the D7100 and D7200 for getting me by.
