Account Bound Achievements... Factions?

[Saranade]

So sorry if this has been asked before, I'm new on the forums...

I just recently rerolled as Horde and am thrilled about the news! I have a huge collection of mounts on my alliance toon that I've worked on for years. I wanted to see if anyone knew if some mounts would transfer cross-faction? Like the Mekigneer's Chopper? Would that become a Mechano-Hog? And I'm assuming that mounts like the SW horses/IF rams won't transfer at all to a horde toon because of obvious reasons...

Can't wait to see my ZG tiger again *_*

Hey, yes all your mounts will be transfered and converted to Horde-equivalent mounts if necessary. SW horses will turn into wolves. For more information, see here: worldofwarcraft [dot com] /info/faction-change/index.xml

Faction change has nothing to do with account bound mounts.

At first they said mounts such as Mekgineer's Chopper / Mechano-Hog, Sandstone drake would not be account-wide, and neither would PVP mounts, but seems like they changed that ( us . battle. net/wow/en/forum/topic/5633973536?page=15#300 ).
So I guess the answer is yes, these things will change depending on the faction.
And I'm not 100% sure, but I think the race specific mounts will transfer the same way reputation transfers when you faction change. For example, if you have all of the Orgrimmar wolves on your Orc, and one horse on your Human, when the MoP launches you'll get all the Stormwind horses on your Human character.
