Achievements/mounts gone in Cata

[Miralynn]

Feh, stupid tiger won't ever drop for me, no matter how many times I try... and yet I got the Baron's stupid horse while I was trying to get my pally the Lightforge set. ("I've done this 49 times now. I swear, at this rate I'm gonna get the damn mount before I EVER see those pants..." *five minutes later* You receive loot [Deathcharger's Reins] "FFFFUUUUUUU...")

Back to some ZulGurub/Strattholme farming again then, what about the mount in Karazhan?
And other achievements/mounts?

The Kara mount should be fine unless they are altering that instance. It is already a low % mount drop. I'm not sure what you could mean by other mounts so:

Invincible: According to Blizzard will be a low percentage drop from HLK
Mim's Head: According to Blizzard will be a low percentage drop from Yogg (probably 0 light)
Frost Wyrm and Uld Proto achievement mounts: They said they weren't happy with having removed Naxx drakes and didn't plan on removing mounts like that again. Likely will stay in place.
Naxx mounts: Who knows, hopefully will be brought back.
White Hawkstrider: Low percentage drop, likely to remin
ZG Mounts: As of right now they are assumed gone until Blizzard states they have moved the ZG bosses to a different location
Rivendare's Mount: Presumably it will still be available in Strat although a mount of a 38+ instance seems off.
Blue Proto: Likely staying
Green proto: Likely staying (go fuck yourself Aged Yolk)
TLPD: No reason to change
Red proto: Could be removed, probably won't be
Polar Bear mount daily: No reason to change
Tourney mounts: No reason to change
Albino Drake/ Dragonhawk: no reason to change
Raven Lord: No reason to change

I can't think of anymore random or achievement mounts.

The Baron's mount will drop from the new version of Rivendare in Strath:

Deathcharger's Reins now drop from Lord Aurius Rivendare.

Pardon the url link above, apparently I'm not allowed to link until I've posted a few times. Just remove the spaces and fillin the dots.
