Blizzard has released details and screens from the big World of Warcraft celebration about to take place at the end of the month.
On January 29th – the date of the actual lunar new year, celebrations occur in Stormwind, Thunder Bluff, Booty Bay and Moonglade. On February 13th, one last firework show will be held in Moonglade. This parallels the Chinese "Festival of Lanterns"; extra lanterns are spawned around Lake Elune"ara (the firework show occurs over the lake).
"Decorations will be placed in every capital as well as in the regions of Nighthaven and Moonglade," said Blizzard. "Revelers celebrating the Lunar New Year will be spread throughout the world (the revelers are concentrated in Moonglade, except for those that show up for the fireworks shows in Stormwind/Thunder Bluff/Booty Bay); the lunar festival specific NPCs can be found in each capital and in Moonglade. There are also other NPCs - spread throughout the world – which are ghost-like elders that players must find and honor, as noted below."
