I read on Aion Source this morning that NCSoft has included an option in your account management to upgrade a standard edition to Collector's Edition for $10 (digital download and in-game rewards only)
So anyone who did not snag a CE but has preordered the game it's not too late to get those CE wings and in-game items!
This upgrade requires you to have an active retail code, so if you bought from anyone other than the NCSoft store you will have to wait until your retail code (not beta) is delivered to you to upgrade.
Here's the thread:
