BM Hunter (which is what I played) is back to using one pet.
Tranq shot is back (Removes 1 magic or enrage effect); I did not see any pets having unique raid buffs (they gave us access to Cat, Dog, Bird of Prey and 2 other pet families to check with).
I couldn't find a stable slot in the dungeon run to see if there was any expansions to it.
There were talent changes. Some abilities were completely moved around.
Level 15 Talents: Big Game Hunter, Way of the Cobra, Dire Beast
Level 30 Talents:One with the Pack, Dire Stable, Chimaera Shot
Level 45 Talents: Posthaste, Farstrider, Trailblazer
Level 60 Talents: Bestial Fury, Venomous Bite, Thrill of the Hunt
Level 75 Talents: Binding Shot, Wyvern Sting, Intimidation
Level 90 Talents: Stomp, Barrage, Stampede
Level 100 Talents: Killer Cobra, A Murder of Crows, Aspect of the Beast
I can't remember all the details to know if the numbers or abilities of the talents changed significantly, I'm sorry. But the new one, Venomous Bite, if I remember correctly was something akin to "Cobra Shot reduces the remaining CD on Kill Command by 1 Second" passive.
It's clear that Blizz is trying to encourage to break up the "cookie cutter" builds that a lot of BM are running with, seeing as many of the 'main talents' commonly chosen are now on the same tier and unable to be picked together. Though, I'm sure there'll be a new 'cookie cutter' build lol
I also didn't see anywhere we couldn't post this info (IDK if it may have already been shown on the demos that were visible to watch on the virtual ticket), but if any mods or random blizz people wish for me to remove this, then I will happily do so!
Edit:
Realized Bendak over at Eyesofthebeast covered this and better than me, my bad xD that's what I get for posting before reading my usual blog haunts lol
Edit 2:

One thing I will say again is for everyone to please remember this is early beta. The final talents will probably look different.
