War Machine *should* have gotten his Avengers Card, but there's a difference between WM's comic-book connection to the team and Falcon's. WM was an on-again/off-again member of the Westies, and rarely appeared in an Avengers book proper. Falcon, on the other hand, was a full-fledged member of the Main Branch and a regular fixture at The Mansion. He has more cache with the Avengers than War Machine did.
Plus, Falcon has been played up as an important Avenger --- albeit a "token black" role for the most part, for now --- in recent pseudo-Avenger fare like the new Avengers cartoon and Superhero Squad. Marvel is definitely "grooming" him for a spot on the movie roster.
