In the WoW blizz store when will they have new mounts/non-combat pets and other things in-game and what r they?

OK they already have the mount crystal steed but they need more mounts in the blizz store i mean only one...its been like forever they need more mounts and new non-combat pets. so what i want to know is if any of you know when they are coming out with new non-combat pets/mounts/ or maybe even gear that u have 2 pay for idk just something cool.
