New pet for Retail and MoP: Sa'bak's Favored. I don't know if they are the same IDs, for Retail it is obtained by purchasing in store, for MoP it is given with a 6-month subscription.

MoP data:

• Species ID 4850
• Rare quality
• Level 1: H 158, P 12, S 10
• Level 4: H 334, P 47, S 39

Had to buy a copy on Retail to figure out its ID, as the game didn't want to give me the data otherwise. It's Species ID 4796 in Retail. Same base stats and breed (8.5/8.5/7 base stats with a BreedID of 3).
