Alongside another that has Palutena and Mario standing next to each like best pals. It's difficult to tell whether this is a hoax or a legitimate leak, since as far as I've seen no official word has come from Nintendo on this.
It's not official (obviously) and it's a pretty bad picture. While Palutena does appear to have a black outline around her like all of the playable characters in the 3DS version do, that's a job easily done by a skilled or patient photoshop artist. Personally, I'm of the opinion that it's either a hoax or she's an Assist Trophy - I'd much rather play as the Eggplant Wizard.
