General thoughts: pets are quite squishy atm, even tenacity. A lot of talents are MIA (almost certainly because of the transition to the new Mists pet system) and health is lower. I solo'd my way through some Wrath dungeons and almost lost Pokee on several boss pulls that wouldn't be a threat to her on live. I'm sure the final version of the pet revamp will improve this.
Pet talent UI/access won't be in beta for another build or two, per GC. Nothing to report except that its missing.
As many have no doubt heard, pets are bugged atm on beta and whatever size it was before you tamed it = the size of your pet. We're seeing spiders half the size of trade district and Devilsaurs that look like they could swallow cars whole (at least 100' tall with Bestial Wrath). Its hilarious, but I'd hate it in a raid/dungeon.
Kill Command has a 25 yard range and causes your pet to lunge/charge the target and deliver the hit. This is a GREAT change.
Trap Launcher is now a toggle, switch it on and every trap is automatically launch-able. Traps themselves got collapsed into a 'tab' kind of like totems, which is convenient but also hides the cooldown on them. Doh!
Bestial Wrath is now on a 1minute cooldown, which is obviously a damn nice buff for BM hunters.
Beast Cleave: this is probably my favorite addition/change. Its a BM spec ability that procs when you multishot, and causes your pet's attacks to Cleave all mobs in melee range for 5 seconds. This is outstanding, sustainable AOE damage that is worlds better than burrow or any other pet-specific gimmick. BC isn't a talent, its a baseline BM spell/perk.
Formerly Surv/Marks only talents like Readiness and Wyvern Sting are available to all specs now, thanks to the redesigned talent trees. And yes, hunters have some really fun choices!
Lots of awesome survivability talents for hunters, including a 15% heal when you Disengage and Aspect of the Iron Hawk, which increases your attack power and reduces all damage you take by 15%.
Trueshot Aura now affects crit and attack power, and appears to be baseline for all 3 specs.
Lynx Rush: a nod to the Lynx form of ZA's last boss, this talent sends your pet rushing through a pack of mobs, smacking each of them for a total of 9 hits that deal normal attack damage. Its a really fun talent, but the damage-per hit is a bit low (1900-2300 at 85) with a considerable cooldown of 2 minutes.
Call Beast: fun talent that summons a second random creature to fight alongside your pet. You have no control over the beast: its basically a DOT that looks like an animal. CB is supposed to have a 30s cooldown, but currently its bugged and can be used pretty much infinitely. So far I've seen it summon a HUGE beetle, a Mists-model tiger and a spirit beast.
A Murder of Crows: summons a flock of 15 crows to attack your target, does around 100k damage over its duration with a level 85 hunter. Currently if you use this on a mob that is ~20% health, the cooldown is reset.
We're currently capped at level 86 so I can't test or access the level 90 talents yet, which is sad because they look awesome.

Beta deleted all my macros and such, which is why my bars are wrecked. >.<
