ok... so we Brits wont get it till 2007 (well it feels that way!)...
From GamesRadar, "So while the delay in the game making the transatlantic transition is deeply annoying (especially since US gamers have it already), the pause should only gain our applause. For Konami and Kojima have already said that British gamers will gain the bonus Duel Mode which, much like the ones in Sons Of Liberty, will let you take on the bosses again in a standalone fight. Similarly, and for MGS completist/sadist only, there will also be a Demo Theatre which will let you replay all those cutscenes that you tried to skip the first time."
makes it slightly better
