I've had a 5N for almost a year now. Fondled a 7 in-store back in August before a trip and was really tempted. The layout and feel in-hand is remarkable.
Two things about the 5N:
1. Autofocus is, IMO, a weak point. I've had trouble with it at times.
2. Using legacy glass is very difficult and, for me, unenjoyable.
Don't know if the 7 is any better on the AF front (looks like the new 6 is) and don't know if the EVF helps with focussing legacy glass.
