The Aion FAQ has been updated with new information concerning beta testing. The entry is now as follows:

"When will beta testing begin?

In lieu of beta testing, Aion fans will be given opportunities to participate in a small number of Preview events before the game's release. In addition to soliciting player feedback, the Preview events will help prepare for Aion's release, as well as provide a great gaming experience on launch day and beyond.

As with Aion's release date, the schedule of these Preview events will be announced in coming months."

More information on the Preview events, including sign-up opportunities, will be made in the near future.
