The beta schedule and possible release date of Aion Online are hot topics right now in the gaming community. Both the limited collector's edition and the standard edition are currently available for preorder, and both Amazon and Gamestop list the release date as Sept. 1. If you're interested in playing Aion, preordering the game seems like a good option. You'll get access to all remaining beta events, some special in-game items and a 48-hour head start when the game goes live.

As for the remaining beta events, Massively has pointed out (via Keen and Graev) that the July issue of  Beckett Massive Online Gamer contains a list of the beta schedule throughout the summer. Here it is, although the dates could always be subject to change:

• June 19-21: Asmodian closed beta capped at level 10
• July 3-5: Asmodian level cap increases
• July 17-19: Abyss only with unrestricted flight and hopefully a lot of PvP
• August 14-17: First open beta
• August 19-23: Second open beta
