Take this with a grain of salt. In interviews for Assassin's Creed: Revelations, they said that Altaïr's vault would contain a weapon capable of finally stopping the war between the Assassins and Templars, and we all know what that turned out to be. One developer also said that we needed to take a look at the comics to get a hint of what the setting for Assassin's Creed III would be (there is nothing pointing to the American Revolution or America specifically in any of the comics).

If Jot Soora really is very important to the overall storyline, I don't think they would be telling his story via a secondary medium.
