Magmaw

It seems sort of odd that we've tested all the current Cataclysm Beta's raids end bosses and subsequent bosses aside from Magmaw. Is there going to be any update as to when this testing for Magmaw, will take place or any notification? I understand sometimes Blizzard is capable of doing "on the fly" notification for raids. But, this boss seems to be the odd one out and some clarification would be appreciated.

Thanks!
