The topic title really says it all, which version are you planning to buy? There's the standard edition, the Hardened edition which comes with the art book and the prestige edition which comes with everything that's in Hardened plus night vision goggles.
Have you decided which one you'll be grabbing yet? I'm waiting on some information on the quality of those NV goggles before I invest in the Prestige. The art book doesn't mean shit to me since the ones that come with games usually suck dick, if I wanted an art book for the game I would go and buy a proper one, not some little 20 page notebook. So yeah, if Prestige doesn't impress me I'm just getting the standard edition which is going to be £55 because Activision knows we suck enough cock to buy it for that price.
