No updates as of yet, or even anything solid about when Closed Beta will happen. Sorry! In the meantime, how about you try subscribing to the Aion Newsletter featured on the official Aion websites? They can be found here-
Aion: The Tower of Eternity - New Fantasy MMORPG by NCsoft - For NA players.
Aion: The Tower of Eternity - For European players.
This is a good way to make sure any Closed Beta information will reach you when it happens.
