With Shadowlands ending, the next expansion’s announcement will likely come at some point after that, which will be interesting to see what direction the game goes.
The biggest rumors going around seem to involve the Dragon Isles and also an old world revamp, which I assume will consist of Kalimdor and Eastern Kingdoms. I don’t know if Saberon would have a role in a Dragon Isles expansion, assuming it would be based on the whole expansion as opposed to being part of an expansion, but the old world revamp has a lot of possibilities.
Kalimdor getting revamped would mean that the Barrens would be updated, which potentially would have the Botani and Saberon that came with us from Draenor in the Mag’har Orc unlock scenario. There is some neat potential to flesh out Saberon as a playable race for either faction, along with hopefully other races people have been requesting for awhile, and some interesting storylines with the Botani, likely in an antagonistic role I assume.
Of course, both of those expansion themes are just rumors. It’s up in the air where we go from the afterlife, though I’m personally hoping to be back on Azeroth again at the very least. I’m hoping we see something come of the Saberon and Botani in Azeroth plot point, preferably with Saberon at least getting upgraded to playable race, though I will temper any expectations when we do get actual information on the next expansion.
I’ll keep an eye out for anything of Saberon interest in the future and report it here. In the meantime, I’ll continue to support playable Saberon as best as I can!
