Since the latest episode introduced the fissure of woe (partly) with new foes, melandrus realm with new foes and reintroduced underworld with existing foes i think it is likely that we will see more godrealms in raids. If i remember correctly, the Devs already confirmed that the Qadim story will continue.
I personaly think that it is likely that Qadim will find a reason to visit the god-realms (He has more than enough reasons, maybe expanding his menagerie or/and finding a new realm for himself). I can imagine him finding a way to travel between the god realms and we, as the players, have to follow him through the god realsm and fight related bosses throughout the god-realms until finally we fight qadim (again?).
