You are creating rumors (like many other people) by misunderstanding how this all works.

If a game does NOT tie our PSN ID's to the save file, then trophies won't be retroactive for that game. Just look at Super Stardust HD...I had that game beat LONG ago, but I just had to play through it again to get the trophies. Why? Because my save file is NOT tied to my PSN ID. I could give it to anyone here, and it would work on their system.

Burnout, on the other hand, would not work for anyone else. My save file is locked with my PSN ID and only I can use it, so people can't 'cheat' and get 101% completion just through copying data.

Don't say "the trophies are retroactive" or even "im pretty sure other games will implement" trophies, because it's speculation and all that does is create false-hype and disappointment later on.
