We have 2 of the main personalities for the Battle of Mount Hyjal happening, and still have other epic/legendary chars to go - Taking a stab at the dark, Im hoping for Jaina Proudmoore to represent the alliance like Thrall is doing for the Horde. Tyrande is too reclusive to represent the Alliance I think.

It would be ages before something like Archimonde would be done, but there are some decent Draenei action figures out there that with a bit of customising would fit in nicely. 

Lots of Scourge figures would be sweet too - Abominations, Ghouls, Cryptfiends etc.

I'm not sure this addresses what you are saying, but...

It is assumed that Jaina is the model on the far left of the group shot photo that first showed us the Goblin Shredder.  Also, the box art depicts Thrall and Tyrande, so they are assumed to be in the set.  However, what rarity any of these models are is yet to be determined.

Got a link to that pic? Im curious to see if its Jaina.

Also, anything that is a generic can act as named mob with modification, and some scenarios could include simple rules for that, similar to how Descent works - "Blah is a Master Ogre with 2 extra armor and 10 extra health"  in descent would be "Sneeds Shredder has 2 extra dice when Defending and attacking, and has 15 health total" for WoW minis.

I think he was talking about the figure rarity in boosters, not stats or the like.  For example, Goblin Shredder will most likely be a common or possibly rare, not legendary, because it's generic.  Tyrande and Thrall would most likely be legendary, because they're such iconic figures in Warcraft (the online game, the storyline, etc).
