Thank god someone's atleast trying to explain it to all the narrow minded ones.
For the tech demo, they wanted to show the PS3's power, and what better way to get people's attention with the game that has alot of....fanboys..., and those fanboys would go rush out and buy a PS3. Seems a bit smart to me.
Also, I agree with the script bit. When they redid MGS for the Gamecube, I'm sure as hell Kojima never intended Snake to like do matrix flips every 5 seconds, and stuff. The only thing that was common between the both games was that it had A) Snake, B) Shadow Moses, C) All the same characters, and D) The same story guidelines. The rest just was destroying of what made the orginal MGS great. Ocelot's boss battle, with First Person Shooter, was like 10X easier then in the orginal when you eaither had to run after him, or plant C4 at the one corner.
I think part of the reason too, is remakes tend to flop horriably. For movie examples, the most recent Friday the 13th, and Nightmare on Elm Street. Then like Twin Snakes, and a few other games I can't remember off the top of my head. Square Enix is a buissness, like everything else. They know FFVII's popular, but would the cost of updating everything to a next-gen counsel, advertising, promotional deals, getting it westeranized, etc etc, balance out with the sales. If it sucks, like it most likely would, you get probably the first inital few mill, but when word spreads out "It sucks it sucks", sales start to plumit, and Square comes like a few mill short of breaking even, specialy in a economic time like this. :/
Then there's just the simple fact that some games are good as they are, and don't need a remake. If we keep remaking everything, it's gonna end up like that one South Park episode where Speilburg and Lucas go crazy and remake ALL there movies, and end up getting killed by the horriablness of the "newnewnew" Raiders of the Lost Ark.
