Well as you can guess Foxy sent me a ping about this.
No problem downloading program and manual from here as I just have.

Re price well that may be the rub. I compared USA prices as at least they show them somewhere
Nikon Mall still only has NX and that is listed as Full version $149.95, Upgrade $89.95
Nikon USA Press Centre announcement - NX2 Full version $179.95 or Upgrade $109.95
Going back to the release of NX then I think the UK upgrade price from NC4.4 was around £75. So given that USA prices have risen the UK price for upgrade may be more like £80-£90.
I will read through the manual before installing and activating the 60 day clock.
