Question

How much processing power does metal gear solid 4 use?

Answer 1

They use the full capacity of the ps3 hardware, the blu ray disc, and the full use of every single processor. All 8 processing power.

It they were going to port it onto the 360 it would be impossible unless they downgrade MGS 4 to fit onto the 360 hardware with multiple disc.
