Just watching one of the Cata beta videos of a guy questing in Blasted Lands. There's some boar mobs in Blasted Lands (Ashmane Boars) that seem to morph between a 'normal' boar and a 'helboar' when they charge which looks pretty cool. The guy checked and they were beasts (although he was a shammy so he couldn't actually try taming them).
Any hunters on the beta know if these are tameable and, if they are, do they keep that little ability when tamed? Cos that'll look pretty cool...
