These pets are different from normal pets, but they're not necessarily more "uber" than others. However they will have access to unique abilities not available to the normal pets that every Hunter can train. A Hunter with this talent will get extra power, but from the talent's associated additional pet talent points and not necessarily from the exotic pet.
It's not just World of Warcraft's vanity pets that are getting a facelift when Wrath of the Lich King arrives. Over at the WoW Europe forums, Wryxian let loose with some additional details regarding a new talent that would enable hunter to tame a new class of exotic pets within the game. As Wryxian (and Koraa over at the WotLK beta forums) explained, WoW's exotic pets wouldn't necessarily be stronger than your normal line of pets, although they would be carrying their own unique abilities.
Here was Wryxian's exact post: The developers are currently working on the exotic pet talent. Exotic pets are exactly that, exotic and not the average run of the mill pet. But whether this name will stick or not, is uncertain at this point. But these will be a range of new pets with unique abilities, that only those with the talent will be able to tame and train. Where do you get them, well, we've not got news on that right now -- perhaps somewhere, exotic!
