That's too bad, I'd enjoy another installment.
It also goes to show that no matter how many times you hear some internet faceless poster scream that a movie has to make 2.5x budget to get a sequel or be deemed profitable you can laugh it off. It's not even rule of thumb. If that were true you'd think a film that cost $60m to make would be fine then with $150m-$175m worldwide. However that article is citing inside sources saying it needs $250m worldwide to ensure a sequel. That's a little over 4x budget for the film.
It's just over $150m ww now, and as much as Cruise has a following in the Asian markets getting another $100m seems to be, well...an impossible mission.
