Datamining hints at Mists of Pandaria Collector's edition mount

A new round of datamining has uncovered an interesting string and spell in the new code pushed with recent updates to the beta -- specifically, a reference to a placeholder for aMists of Pandaria collector's edition mount. Here's the string/spell change, courtesy of MMO-Champion:

[PH] MoP CE Mount - [PH] Summons and dismisses a ???. This mount changes depending on your Riding skill and location.

Traditionally, collector's editions of World of Warcraft expansions included a pet, usually a whelp that resembles a key figure or theme of the expansion. The original collector's edition of WoW included three pets, the Zergling, the panda cub, and the mini Diablo. No collector's edition has ever shipped with a mount before.

Here's the kicker: There is also a string and spell in the new build for a collector's edition petas well, which means more stuff packed in to this next release's premium package.

Does upping the ante on cool in-game stuff, from pets to mounts, put the collector's edition of Mists of Pandaria closer to your shelf? As a consummate purchaser of Blizzard collector's editions, I will be shelling out the cash notwithstanding. However, it would be nice to see a bevy of new rewards in the collector's editions other than just the whelps. They will, however, be excellent editions to my Pet Battle Army. What do you think the collector's edition mount could be?
