Well IGN.com has a new preview for Burnout: Legends. It has some new information but the rest we have known for a while.
New things to us are:

-Legends will consist of the best tracks, music and cars from the previous Burnout games.
-There will be 100 crashes.
-Multiplier icons and Heartbreakers icons are not in the game.
-The Pursuit mode has been added from Burnout: Point Of Impact.
-Burnout trophies will also be in the game.
-There will be no online play.
-There are 25 special cars that you can unlock, but each copy of the game only comes with 5. In order to get the other 20 cars you must play against them.
