Yeah. THAT just happened.
Roslyn and I are very excited. No knowledge of genders yet, although we do know they are fraternal (and not identical). Ros and the twins (it still sounds weird to write and say it) are all healthy, albeit tired.
Tali is excited and rooting for sisters. Mac is excited, as he wants playmates to climb on. Professor Tiggens, however, is not excited, as he will drop two more spots on the alpha male scale.
We expect the twins, codenamed: Azekah and Sochoh (for reasons unspoken) to be born toward the end of May or early June, just prior to the beginning of Season 2 of the Azekah archaeological excavation beginning mid-July, 2013.
