So for the record not predicting nor saying any of this is gonna happen or that any of this is fact; just simply evaluating WOW's lore, blizzards pattern with expansions, and hopes for 91 to 95. So feel free to put any input or dopes or ideas or correct any fact errors i post =)
#1 SO Blizzards pattern so far if we look at it is BC 2 new races and outlands, WotLK gave us a new continent Northrend and a new Class Dk's, Cata gave us a remake to Eastern Kingdoms and Kalimdor and gave us 2 new races, and MoP gave us a new Continent and a new class Monk's similar to WotLK but we were also given a neutral race Panda's. So if we look at this we can see that BC and Cata share some similar points as they both introduced new playable races to each faction and they also broadened the race class combo (ex: Dranaei Shaman, Blood elf Pally, Dwarf Shammy and Tauren Pally). And if we look WotLK and MoP share more similar qualities they both gave us a new continent and a new class slight difference was MoP also gave us a race 0_0?.
#2 And if we look at lore, and i just wanna state this is from my knowledge of Lore, 99% chance i may miss some things or may not know small pieces and overlooked them. That said currently Deathwing has been dealt with the aspects have become mortal, Thrall as stepped down and given a red Orc the title of Warchief who is slowly but surely become more drunk with power and rage. We have stumbled on Pandaria and are mainly focusing on the actual war. Some things i know we might see or may be used in the future is Wrathion and the Black Dragon flight story is continueing possibly in this expac, Ashzara is still out there, yet to Deal with the Burning legion, possibly some more lore with the Aspects and the Emerald Dream, maybe a 2nd go on the new LK and a return to Northrend and more DK lore, a trip back to OUtlands to deal with the Burning Legion, or maybe even an invasion on Azeroth from the burning Legion and of course Sargeras.
#3 SO basically my thoughts and they are just ideas are the following:
Looking at the pattern and Lore i think next expac 91 to 95 we will have dethroned Garrosh, and maybe even have a sorta truce between the horde and alliance even if only temp. They may not give us 2 new and last races to each faction and maybe a revamp on Outlands where we go back becuase we find that the burning legion is stirring up again. So we truck back to fing the BL much stronger and with a bigger plan to bring back Sargeras, we deal with Asharza and KJ. Then finally 96 - 100 possibly the last expac we get a new place possibly in space or the WOW version of hell??? and a new class Demon hunters for sure i know they are coming and its a slow build up to the final battle or end or re imprisionment or helping the titans with Sargeras.
Plz tell me what u guys think or hope i would love to hear some insight = )
