My predictions: new masteries (obviously)new Elite Specializationssome new features like actual player housing, fishing, or other requested featuresmore integrated maps and story, made possible by....season pass that be purchased from gemstore or from a retailer. This gives guaranteed unlocks for entire season plus HoT/PoF if they are not currently owned. Could also include some other gemstore items such as character slots, 80 boosts, and skins. Players who own both HoT/PoF would be able to unlock episodes for free, but since the episodes will be more integrated, if they miss a free unlock, they will be required to buy the season pass--possibly at a prorated cost to take into account existing episodes that are already unlocked.I think the last item is very likely, as they will need some new way to monetize the game if they are no longer selling expansions.
