The message is UNCLEAR. Exactly what is the "situation" ? The message is not well written. A professional message would include statements that convey the reason for the delay. For example: We will not be releasing Crystal Isles on the 4th as planned because (insert real reason). The in-game celebration is delayed as well. Both will happen on the 11th.
Or don't clarify anything or re-write the message because you REALLY believe in delaying a software release and game event because somewhere someone did something. Next it will be someones hurt feelings that will delay the timely release of the latest expansion.
