WorldOfWar.Net relays a warning from Blizzard for
World of Warcraft
owners planning on installing the Wrath of the Lich King expansion for the
MMORPG. It seems the expansion will ship with version 3.0.1, so if you've still
got the version 3.0.2 patch on hand, you are advised not to delete it, so you
can easily get back to the latest version after installing the expansion. Thanks
Ant.
