I would love me some trophies for Vegas 2, I never played it that much because I just got it as an inbetween game, but what I did play of it was fun.

Still, now I would rather play something newer and that has trophies.

 I'm right there with you man.

It's not gonna happen.  As I said, it's too much work for too little return.

They have to figure out what the trophies would actually be.  They have to implement a trophy system.  They have to then implement the trohpies into the game.  They then have to test them.

That's a lot of work and the game has been out for too long to care.

GT5P, Heavenly Sword and Metal Gear would be started over by me if they got em. Well maybe not GT. Too much time wasted if they aren't retroactive.

True, but the same could be said about Uncharted which has been out much longer than MGS4. The could probably put a patch where they give trophies for the achievements which was pretty much what Naughty Dog did for Uncharted.

Still crossing my fingers

Although some emblems aren't particularly suited for trophies (Big Boss one would be insane), a good amount of emblems can be transformed into trophies for the game.
