Color changing pets gone in MoP????

[zedxrgal]

Are all the color changers being done away with??
Has anyone been able to confirm their existence in beta?
I rerolled my goblin huntress to ensure I had the color changing raptor in the hopes it would be grandfathered in so to speak. I also have the color changing NR worg (but had him a LONG LONG time) on one of my hunters. Another has the color changing spiky crab. I'd really hate to lose them if they're completely done away with. I'm very attached to these pets as color changers.
I will be broken hearted if my color changers no longer color change after MoP arrives.
And evidence of their leaving completely?

This has been known for some time now

Anything tamed on the beta will stay the same colour you tamed it as, no matter how many colours it comes in. This is great in most cases as things that weren't available on a colour stable model before now are, and makes it much easier for them to add lots of colours to mobs in Pandaria without having them all be colour-changers, or have to add loads more NPC ids than they need to. But yes, for anyone who likes colour-changers they won't be able to get any new ones come MoP.

However, last time anyone tested and reported (some patches ago), colour-changers that were copied into the beta from live retained the ability. So anything you hd already tamed was grandfathered in. But to my knowledge that hasn't been checked recently.

I just copied my goblin hunter over to check her raptor. He still changes colour in beta, so hopefully it will be grandfathered, but I'd chance on it not just in case of disappointment.
