It seems that those expansion files released with the Test update weren’t all that early after all.

According to the French version of SOE’s EQ2players.com site, players will see the return of the god Rodcet Nife in Update 45.  In addition, it appears that the Void will be invading Norrath in this upcoming update, fueling speculation that the upcoming expansion (rumored to be named “The Shadow of Odyssey”) will be centered around the Void. 

The relevant text was here (translation below):

L’événement de Rodcet Nife sera en live avec la mise a jour 45.
Un mystère volontaire entoure cet événement et tous les suivants seront de plus en plus impressionnants menant vers des invasions de grande envergure des créatures du Vide à travers le monde pour toutes les niveaux.

Translation:
