I've spent the afternoon visiting all the known vendors in Outland, including faction vendors. Sadly, I'm having trouble finding some of these new recipes that are supposedly being added. I only found one of the new Alchemy recipes (CE faction) one Engineering and one Jewelcrafting recipe (both Consortium). I have yet to see any recipes on a normal vendor, but I'm still checking them. I did find the two new Alliance Cooking recipes at Toshley's Station as promised. As for the others, they either they really hid them really well -- like on instance vendors (sorry haven't checked those yet) or they added them as drop loot :(
The quest front is even worse in terms of luck. I don't have epic mount skill on either of my level 70 girls, I'm madly farming gems on my live server to raise the cash. It would appear that none of the quests are even visible to you unless you have the riding skill, no white ! marks or anything. I found a camp of netherdrakes in Shattrath that look suspiciously like a "shopping" area, but the one guy there won't speak to me at all. I also visited the druid trainer in Moonglade but found nothing that referenced the epic mount quest. So I'm at a total loss on how to kick off these new quests. I suppose I need to try and transfer another toon over with some money so I can try to get past this hurdle. How annoying!
