The Phantom Menace was shot on film, they did the digital transfer to 1080p (Lucas, as usual, not thinking ahead), it would have to be remastered to 4k. It could happen.
Edit: Episode II & III were shot with a Panavision HD900F (not enough posts yet to throw the link up here, ugh), those two would be in 1080p. Then again, who cares. As long as the first 3 can be transferred, I could care less about the second three....
