Oh come on. We just had the MGS4 gets trophies thread so then you make a thread about VC on the same topic with no indication that this is just a hope. I was (kinda) excited that the game was getting trophies for a moment there -_-
Honestly it's very unlikely. It seems like the reason MGS4 is getting them is because of the budget re-release.
Although honestly thinking about it I'm not entirely sure I like adding trophies later into a game. For me I got my PS3 late enough that with Uncharted they were already there. Off the top of my head I have NG:Sigma and VC that don't have trophies. I would actually be kinda annoyed if after me having played those games suddenly people who played them new would get trophies and I wouldn't.
