I check the Serebii EventDex for upcoming events. At the moment, I do not believe so, but I will check.
EDIT: These all started in 2012, but currently, you can get the Sinnoh starters with their Dream World Abilities. The events end on July 31.and are USA only for B/W2. You can get a Dream world Scizor as well that is for ALL Gen 5 games for all of North America ending on February 21.
EDIT 2: I do not know of any announced to start in 2013, but I know there'll be some. Anyone who has the power to edit this may edit this as events come along.
All the Pokemon are Level 10.
