The 650+ pages of responses to the usage of real names on the WoW forums are indeed being heard by Blizzard. Here are some of their responses:

 

Drysc:

One important point which I don't believe has been relayed yet is that the switch to showing RealID on the forums will only happen with the new forum systems we're launching for StarCraft II shortly before its release, and a new forum system for World of Warcraft launching shortly before the release of Cataclysm.

All posts here on the current World of Warcraft forums, or any of our classic Battle.net forums, will remain as-is. They won't (and can't) automatically switch to showing a real first and last name.
All posts in the future on the new forum systems will be an opt-in choice and ample warning will be given that you're posting with your real first and last name.

 

Nethaera:

Just to respond to those that don't think we read through all of these responses and threads, we do and have been. We will continue monitoring feedback as well.

We put a lot of thought into this change and have a long-term vision for the Real ID service and wanted to make sure that we communicated ahead of time and very clearly as to what will be changing and how. Keep in mind that posting is optional, and we recognize that some players will choose not to utilize the Real ID feature in game or post on the forums and support everyone's individual choice on using or not using it.

This is obviously new ground for us and for you as well, but we want to make sure we're creating a great social-gaming service that people will want to use. We just want to make sure that if people are sharing feedback, that they keep it constructive, and yes, as I said, we are reading.
