Assuming that the MGS series is fairly driven by plot and setting (I've only played the first one) I doubt it would matter to most people that they're using the MGS1 engine.
The Wii has already gotten tons of PS2 ports I don't see how the MG3 engine would be any different. They wouldn't necessarily port MGS3's engine anyway they might just build a new one from the ground up or something.
