Metal gear wont be using mgs4 engine :(:(:(

Metal Gear Solid: Rising won’t be using the same engine as Metal
Gear Solid 4: Guns of the Patriots. Instead, Kojima Productions is
building a multiplatform one from scratch to support the PC,
Playstation 3 and Xbox 360.Despite some initial concerns, they assure their fans that the multiplatform development won’t compromise the game in their latest podcast.
In fact, Kojima Productions even promise that Metal Gear Solid: Rising
will end up looking better than Metal Gear Solid 4: Guns of the
Patriots.Still, Metal Gear Solid 4: Guns of the Patriots is one
of the best looking games so far this generation. It is a shame to see
it not being utilized again. Perhaps Playstation 3 fans can find solace
in this announcement by the fact that it also lowers the chances of
Metal Gear Solid 4: Guns of the Patriots being ported to the Xbox 360.
