It's quite possible we could get the Raccoon, and not the Tanooki Suit, or the Tanooki Suit, and not the Raccoon.
Personally, if I had to choose, I'd go with the Tanooki Suit. But unless they have ideas for the statue transformation as a 3D Mario gameplay mechanic, they'd probably go with the Raccoon, which was part of their marketing for SMB3 and was thus more iconic.
