OP - MGS4 is the best game ever and its too bad you'll be missing it over some stupid dispute or disagreement between a couple of multi-billion dollar entities. Who cares about the exclusivity and if it poked fun at DVD/MS? Play the game for what it is and enjoy. The way I see it, more games, especially ones that are universally acclaimed, are always welcome on my console. Look at PS3 fanboys. They are not complaining about getting Lost Planet, Bioshock and Eternal Sonata. Even today many of them are anticipating TOV, Dead Rising 2 and the next Bioshock. MGS4 won game of the year last year from 10 places, and at least 30 other awards from various sources. Bringing it to 360, especially with extras, would make it a first day buy for me and I already own the game.
I also expect MGS4 360 to become a million seller very fast, unlike year old ports for PS3. Times have changed, its not Q1 2007 anymore. PS3 has some of the best games, allowing people on 360 to play them will atleast make MGS available to 50% of the market right now.
I hope you change your mind cuz I think you'd love the game.
