Not sure if these were already common knowledge or not, but I thought I'd chime in with the info anyway.
I saw two new Movie Moments two packs today at Wal-Mart. Mr. and Mrs. The King was the first one. There were at least three of them, scattered in with some older packs. Also saw Mia and Tia, Lightning McQueen's twin sport car groupies. Only saw one of them.
On the back of the card, it shows Rusty and Dusty Rust-Eeze, and Flik and P.T. FLea. Didn't see them.
Oh, and check the Halloween section at Target. There's a Cars Halloween assortment there. Three Cars characters: Cruisin' McQueen, Doc Hudson, and the purple Ramone. They come on blisters that are pumpkin shaped, and have a still from the movie from the scene where all of Radiator Springs is out for a nighttime "stroll". The Cars all look like the regular, normal versions, but I'm no expert.
