Forsaken Dreams

Here is the link with all of the prepatch questing info for the mounts. SPOILERS are included since it's a walkthrough.

Basic gist: You have to do the questline once on Alliance and once on Horde if you want both of the mounts. After that, once you start the questline on your alts and get to Stormwind or Undercity (after completing at least once on another toon), you will get the option to skip the quests and go straight to the dailies (it will port you to Darkshore the first time). The dailies provide 210 ilevel gear. Be sure you do all the dailies, even if the piece of gear is a repeat. The gear has a chance to Warforge, Titanforge, get a socket upgrade, etc. I have heard folks saying they got 225, 240, someone even said a 260. So have fun!

Here is the Coming Soon section in wowhead:
The Burning of Teldrassil questline will start on July 24th and continue over 3 weeks which will reward the War-Torn Reins of the Undercity Plaguebat or Smoldering Reins of the Teldrassil Hippogryph mounts.
The Battle for Lordaeron event will unlock approximately 1 week before the expansion's Launch.
