Naga has a decent possiblity of being the next WoW playable race
Why this is possible:
-Next expansion likely to be south seas/kul tiras based, which is perfect opportunity for this sea based race
-Naga have been an established race since vanilla
-Naga have recently been our allies, not just enemies
-Can speak unlike murlocs
Concerns:
-Hard to make gear make sense, they no feet/legs
-Everyone hates swimming in WoW
