All we know is that we won't have Naga Rogues or Monks, Kick, Spinning Crane Kick and Blackout Kick are out of the option. While you could substitute a tail slap for Kick and Black Out Kick with SCK that's kinda hard.
On a more serious note, I'd rather have sub races than new races. The reason for that is mostly that I'm an altoholic and want to play em all. Well except undead, never liked them.
