I also would adore playing a Wolvar. Wolverines are one of my favorite animals, and the Wolvar are just so adorable and grumpy. XD
Another would either be Ramkahen or the cat humanoids that some trolls turn into. The models just appeal to me, especially the Ramkahen models.

And lastly... Furbolgs. I love their Northrend models, and I think they'd be a fun race to play! ^^
So, which races would you play?
Edit: I forgot to mention Jinyu! They're really cool looking and could totally have some really neat racial abilities!
