Weird thing to focus on, but let's see...
San Diego Studio makes a best seller in USA each year.
Bungie still has production autonomy and I assume that will keep going if Marathon is a success, otherwise they will be treated like another Sony studio and have their publishing department shuttered.
Haven is the most likely one here, but hard to say when we don't know much about their game (though I personally don't like the look of it).
San Diego Studio at the very least makes that last option a very dumb thing to vote.
