Bleh, I never liked MGS in any case. Had the first one on the original Playstation and hated it. My brother bought it and beat it about ten billion times but I could never be bothered, it sucks. I don't like the Japanese styled games much, something about it just doesn't appeal.
Plus the whole stupid Otacon video about entering Disc 2... that's just stupid, arrogant and uncalled for. The 360 has much faster load times than PS3 simply because Blu Ray is hellishly slow. I'd rather swap discs than have time to go and make a cup of tea between cutscenes.
I really hope that MGS4 bombs. Apparently it has horrible AI and is 50% cutscenes, but the fanboys sure will love it.
