Realistically, this shouldn't open above $200 million, it just won't happen. If it does, then I think Christopher Nolan should be solely responsible for it, lol.
All kidding aside, tracking for MoS is tough and there aren't a lot of companies throwing out specific numbers it is more of the same $100+ million expectation. The reason is because beyond $100 million anything could happen. I still expect $130-$150 million OW.
BoxOffice.com projection still sits at $115 Million OW and $357 DOM final which is pretty darn good by today's standards. I think the DOM total is right on the mark but could end up a little higher like $360-$380 million and that's if it has some legs. The RT reviews aren't very encouraging but again, fans and the GA will be the ones who make or break this film.
