Let's not kid ourselves, everyone of you has bought this hook line and sinker. The real reason it will be delayed is because they will have to patch this thing a week after launch for all of the stuff they missed. Especially balance. They are mitigating risk of releasing broken end game raid content, due to class imbalances, lvl 60 issues, or other tweaks that need to be made. This gives them time to focus on the launch and server stability, and then a few last minute fixes before they open it up.
