Missing Modern Warfare 2 NVG Edition (UK)

[Gemini-Phoenix]

I was just browsing the video game sectuon in Morrisons, when I came across what initially appeared to be the Modern Warfare 2 Prestige Edition for just under £50 quid. However, upon closer inspection I noticed a few differences:

1) This edition was called the "NVG Edition"
2) The box artwork mimicked the cover artwork for MW2
3) The game included inside is NOT the Hardened Edition, just a standard copy of the game

It's simply the game plus the Night Vision Goggles (plus moulded Soap McTavish head)

Here's an example found on eBay:

I initially suspected that these may have been some kind of European import, but the box artwork displays the BBFC logo implying that it's a UK release

Has anyone else noticed these popping up? I've not seen this edition before, and have no idea when it was released. Is it new old stock from two years ago? Or has it been recently silently released? It seems a bit odd that these suddenly surface around the launch of MW3...

Does anyone know when these were released?
