Downloadable content is currently in the works for BioShock Infinite, and there's reason to believe that Elizabeth won't be the player's AI companion in the first add-on.
According to the LinkedIn profile of a senior animator at 2K Games (spotted by Superannuation), “BioShock Infinite DLC1” will boast a brand new sidekick. The animator's resume notes that he was responsible for “providing animation and R&D for a new AI companion character."
