Last year's December Direct, we got a Fire Emblem: Awakening release date, an Animal Crossing release window, eShop announcements, DLC for NSMB2, and various previews of several 2013 3DS and Wii U games, some of which were released in the second half of 2013. So I think we'll likely get no HUGE news, but rather some nice tidbits for both platforms.
Love and tolerate.
