We know that they are working on a Wii title, but now thanks to a Gamasutra job posting, they have teased the title a little bit.

Big Huge Games, developer of the award-winning real-time strategy games Rise of Nations and Rise of Legends, is expanding into a multi-team, multi-genre company. We're looking for an experienced, exceptionally knowledgeable, talented, and motivated Concept Artist to contribute to our upcoming Wii title (trust us, while it’s yet-to-be-publicly announced it’s gonna be an incredibly fun and quirky title that’ll be a concept artist’s dream).
