Clarification on pet talents

In the comments thread on the post yesterday regarding Wowhead's new pet talent calculators, many of you seemed somewhat misinformed and accused the calculator of being buggy. To set the record straight, here are some fun facts about pets and pet talents in the current Wrath beta:

• The +damage/+health/+armor modifiers have been removed from pet families. Instead, a pet's modifiers depend on which of the three pet talent trees it has: Ferocity, Cunning, or Tenacity. However, Blizzard will be implementing pet-family-specific abilities.

• Hunters get one pet talent point at level 20, and one every four levels thereafter.

• The total number of pet talent points available at level 80 is 16, unless you are a Beast Mastery Hunter with the 51-point talent Beast Mastery, in which case you get an additional five points, for 21 total.

• Each successive tier requires three points per previous tier to unlock (compare to five points for player talents). The exception is single-point talents such as Charge or any of the tier 5 talents, which require five points per previous tier, according to their tooltips; the exception to this exception is Boar's Speed.

• This means that the tier 5 talents are only available to BM hunters, since they require 20 points to unlock (again according to their tooltips), and any given pet can have at most one of them at a time.

• The last two points are based on how the tooltips read. However, this is not how they're currently implemented in-game; in the beta right now, All talents require three points per previous tier to unlock, which means non-BM hunters can get them as well. So there is a discrepancy between how the tooltips read and how it actually works when you go to spend the points. I'm guessing the tooltips are correct, since that would keep the tier 5 talents BM-only, and prevent hunters from getting more than one tier 5 talent.

• Update: The tooltips are incorrect. Ghostclaw confirms that all tiers require three points per previous tier, which means non-BM hunters can get the tier 5 talents.
  

All of these facts are confirmed by sources in the beta. Of course, it is beta, and any of this is very subject to change, but that's the way things stand right now. By the way, how amusing is it that moths will be Ferocity pets? Ahhh, run! Ferocious moth!
