Aion teases a major update, probably version 5.0

There's something big brewing in the Aion realm and the short and enigmatic teaser doesn't tell us much about it. However, fans were quick to notice that this update (which actually was revealed simultaneously for Korea and US) is probably tied to a 5.0 update – the Korean teaser even included the 11.11 date on it (November 11, 2015, in case you're not good with dates), but we would say it's unlikely the update launches in the exact day in both regions.

This alleged update is also said to be making some changes to the Asmodean faction, once again just some speculation but we would say that it could very well turn out to be true. If you want to follow the developments and speculation on this teaser you should keep an eye out on this Aion thread.
