I gotta be honest, I don't know anyone whose ever thought Trek had the potential to stand with the billion dollar films. As big a Trek homer as I am, I thought the film would do $600 million worldwide. I saw lots of posts that put the total at between $450-650 million worldwide. No one I know thought Into Darkness was a film that was going to do the same business as Iron Man/Superman. So I'm not exactly shocked that Trek is in the tier below them when it comes to box-office performance.
Futuristic action/sci-fi generally doesn't sell as well as contemporary action/sc-fi.
I don't think Trek will ever do a billion, but I do think it has a higher ceiling than either ST09 or STiD would lead to believe.
As I said in the other thread, I think a good zombie alien invaders movie has a $600-700m potential.
