Wooly White Rhino mount

Hi all,

I wanted to ask why the mount - Wooly White Rhino isn't on a store for icecrown players? I think many people would love to buy/own this mount including me. The mount isn't obtainable ingame at all and I even think not from any GM's event. Even on blackrock server u can buy it via rating/arena points.

Thanks for the answer.

I assume they are saving it up for some cash in the future.
