I was the guy who put up the first shots (that I know of anyway) of Soriid on beta servers on these forums.
I am in the process of TRYING to tame Grunter on live to do the same thing, but I have yet even seen him on live. Winny actually tamed him on live, but as far as I know isn't going to copy that character over to the beta server again... even though I have copied my 71 Draenai Hunter (Misfortune) over about 3 times already "testing" pet skin changes... I am running out of copies!!
I am more interested in trying to find, or find out about, the blue scorpid in the beta... because I seriously can not afford to drop two out of three favorite pets (Aotona, Skoll, and Arcturis) considering I have already dropped Loque'nahak and Gondria on my 80 Orc Hunter (Tapeworm) so I can get the white/brown Silithid and Soriid. Dropping two more would net me Grunter and the Blue Scorpid, but I am HOPING we get to see the increase of Stable slots pre-Cata... but I doubt it.
After everything is said and done if I MUST choose between getting Grunter or the Blue Scorpid pre-Cata (and dropping probably Skoll) I am going to choose the Blue Scorpid... and hope Grunter is still tameable AFTER the beta and skin change.
