2009 has been a great year for WOW. With its peak being the Icecrown Citadel finally opening up, and with, in the next few week, the lich king encounter itself will be unlocked.
The next major patch will include new features identified with the Cataclysm Expansion, making 2010 even a greater year for WOW.
If you haven't done so already, you can catch up on the Cataclysm expansion and its new features on our Cataclysm Guide page. Also take not that I will be purchasing and reviewing the top leading and most popular Cataclysm Guides on the Cataclysm Leveling Guides reviews page.
Best wishes everyone, and have a great 2010!
