Blizzard has announced that a new "Celestial Steed" flying mount and "Lil XT" companion pet will be added to the Blizzard Store. While Blizzard has sold companion pets via the Blizzard Store for several months now, this marks the first time that Blizzard will be selling a mount. No pricing is currently available, however MMO-Champion is reporting that the mount's speed will scale based on the speed of your existing mounts.
