Sometimes it feels like Blizzard might run out of world threats or new continents for future expansions, but I know there is still so much we haven’t seen yet. Here are some predictions and possibilities. Thoughts?

Return to Northerend: There are a lot of stones left unturned in Northerend. Bolvar is still there and there’s some potential for him as a villain. The spider kingdom is still there. There’s a lot going on quite frankly, and it stands to reason we could end up back there for an expansion at some point.Underground expansion: this is an idea that has been toyed with for YEARS by fans, and even developers to an extent. Blizzard actually made Azol’Nerub a whole zone in Lich King but scrapped it because the idea of an underground zone was too risky. There’s a LOT of lore stuff going on “underground” in Azeroth(spider kingdoms, dwarf caverns, goblin cities, old god stuff). There’s a lot they could do with an underworld X-Pack. Except there’s one problem: skyboxes, art design, environment, etc. playing in dark underground zones for an entire expansion with no skyboxes or anything could get very boring and depressing, and it would take some serious artistic design to combat that.New planet expansion: while Argus was a really cool concept and a great patch, the even bigger implication of that patch is that there are so many different worlds out there that we could now potentially access. If Blizzard did ever run out of “on-Azeroth” ideas, they could simply send us to a made up new planetVoid expansion: this kind of goes along with the above idea, but we now know the void are the major threat in all the universe. It stands to reason that we’ll have an expansion totally centered around them at some point. We may even have a few centered around the void just as we’ve had multiple Burning Legion expacs, but that depends on how long Blizzard wants WoW to go on for.“Other side of Azeroth”: I know most of the globes in the game don’t really depict anything to the east of Eastern Kingdoms or to the west of Kalimdor, but if I recall, Blizzard has still been pretty ambiguous on if there is anything there. They may have said there “isn’t”, but if Blizzard really wanted to go that route, why not just make the whole world a globe on the map? Why not show zeppelin and boat paths go right from eastern kingdoms to get to Kalmidor and Vice Versa? Why not have any characters mention sailing or traveling to the other big continent from the other way? I think because they purposely want to keep the option open that there is something else back there. What could it be? More islands maybe, but they could always add a massive continent.Time travel expac: I know I know, WoD was a disaster. But there’s a lot of cool stuff they could do with pre-sundering Azeroth. Imagine an expansion where we go back in time and explore Azeroth when it was a supercontinent with varying troll and insect empires. That could be really cool. The only problem is that time travel in fiction is almost always a disaster.There are many other ideas, what do you all think?
