As an observation I think it is just funny how everyone has been desiring an upgrade to a D700 almost since it came out and now it may not be announced till after the D4.
As a reminder the D3 and D300 were announced together and the D700 came out about a year later.
I looked back and about 18 months ago (for my own purpose of looking for future expense planning) these were my estimates based on previous releases (not announcements):
D4 Sept-Oct 2011
D800 July-Aug 2012
D400 Jun-Oct 2011
D7100 Sept-Oct 2012
D5200 Apr-May 2013
D3200 Mar-Apr 2012
These were all before the earthquake and flooding. Move the D4 & D400 and everything else sort of looks to be on key. I still had the D800 at mid 2012.
Just thought it was interesting as I was going though my EOY budgets.
