Blizzard has previously told us that they plan to renovate as many of the holidays as possible, but from what we've seen so far, the Lunar Festival hasn't really recieved any of that love-- as Lodran says, players who've done the Lunar Festival quests in the pasts aren't finding anything new to do this year.
Not that there's anything really wrong with that-- Omen is still out there to be taken down, and for a lot of people, Omen was the first raid boss they'd seen (in fact, he was the Horseman before there was a Horseman-- a seasonal boss, except that Omen didn't drop epic loot). And lots of people are still having fun running the old Lunar Festival quests and turning those in.
But it is too bad there's nothing new yet. Guess we'll have to wait for Love is in the Air and Noblegarden to see if Blizzard's done any more seasonal updating.
Love is in the Air and on WoW Insider. Check out our continuing coverage of the event and our guide to earning the achievement. And you better hurry; the holiday only lasts five days!
