Question about Cata Guide Upgrade

[rahl]

Hello!
I have the WotLK guide currently but I purchased Cataclysm. Will the guide work at all or do I need to purchase the upgrade? Was wondering if the whole guide was changed or if Cata upgrade just adds 80-85 to the guide. Thanks!

All of the 1-80 content that you owned will be updated free of charge. If you wish to have guides that cover the 2 new races and the 80-85 content then you'll have to purchase the guide upgrade.
