Did we all of a sudden forget how incredible Interstellar was visually? I think even the biggest critics of that film couldn't deny the movie was visually stunning. Yes Wally Pfister is a huge loss, but don't be silly and dismiss Van Hoytema. He's a brilliant cinematographer... Nolan would be very grateful and happy if he actually comes back to shoot this film. Remember, he chose Van Hoytema from a whole group of cinematographers. Just look at this guys work on Her!
I would be very happy if Van Hoytema is back on board. He's one of the great ones.
I think there are possible other candidates, but as I state in the Podcast, I think Hoyte being able to handle larger cameras and deliver that hand-held aesthetic is what's going to set him ahead of other cinematographers.
