Available in the LOTRO Store until August 16, 2012 is the newest class themed mount the Lore-master Steed.
Lore-masters are seekers and practitioners of ancient lore and knowledge. Their steeds must be arrayed such that they can bear numerous scrolls, parchments, and writing implements. This mount is blanketed in a deep blue embroidered with silver stars to reflect the night sky, the realm of Elbereth Gilthoniel, revered of the Elves who are the greatest of lore-masters.

Like other class mounts, this is a 68% speed with 250 morale. I have not seen any confirmation yet but given that it is a class steed, I am assuming that the cosmetic pieces of this steed will also be available for your warsteed after Rohan’s launch.
The purchase is per character so make sure you are buying it for the character you wish to ride this steed (you know like your Lore-master perhaps).
If it is just the stats you are looking for there are in-game alternatives such as the Elf Ambassador and World Renown horses for example have equal stats but a different look, of course. If it’s the look of the horse you are enamored with, this is your only option.
