As for the upgrade price -- it seems to be loosely correlated to the J inventory, but in this case I think it's also giving you a discount for having purchased an expensive fare in the first place. It could go up even the ZN space goes away; if Z goes away also, I'd say it's almost certain to increase.

Looking at the seat map, though -- there is exactly one odd-numbered window seat available -- 17A. I'd be tempted to pay the $649 just to secure it.
