Even if it does come and is as capable D750, you'll be paying a hell of a lot more for a 5D4.
I'd like to wait to save me swapping over but with the first wedding of the year in April next year, I can't really afford to wait. I'd rather make the change now and have 3 months to get used to the D750 at a much cheaper price.
Much easier than sell up and get it all again though. Give and take, £1k more for each body vs getting 8 lenses again, new flash system, remote triggers etc.
They bloody match it....
