Not sure if Bungie has any plans (haven't really looked around or seen anything in the news feed), but maybe something 'March Themed' would be fun. Since it's the month of St. Patrick's Day, how about a free-for-all event? Something like "Belfast Brawl"? Awards can be March themed shaders and emblems. Maybe make it a melee-only type match, where you can only use melee (not swords)? Just a thought. :p
