Wowhead recently datamined some resources from the upcoming Battle for Azeroth expansion and revealed the upright orcs. They have a their own animation set, brown skin and they don't look like bell-ringers of Notre Dame.
Thrall was one of the few orcs who could stand tall before this expansion and players have desired that model for their characters for a long time. Now they will have chance, as the Mag'har orcs are on PTR right in this moment. If you don't feel like booting up PTR you can always have fun with wowhead's .

Mag'har literally means ''uncorrupt'' in Orcish language and as the name implies, they are the orcs that managed to save themselves from Burning Legion's corruption. The first time players encountered them was back in The Burning Legion, in Nagrand. They still have the standard orc hunched models but these will get updated with the Battle for Azeroth.
As previously announced, Mag'Har aren't going to be the only allied race for the Horde. Highmountain Tauren, Nightborne Elves and Zandalari Trolls will also be joining the fight. Zandalari in particulary have interesting new models for their druid forms which can also be on wowhead.

Alliance will get Lightforged Draenei, Void Elves and Dark Iron Dwarves. Void Elves are the good looking additions to the alliance side, with Lightforged looking less blue I guess and Dark Iron Dwarves are the same people you were beating up on in Blackrock Mountain.
Even though I'm usually an Alliance player, I have to hand it to the Horde - they got the good stuff this time around.
