Fantastic Four 3

http://boxofficemojo.com/movies/?id=fant...

I was looking at the results of the last FF movie compared to the first.
The 
first brought in 3x what it cost to make worldwide. The 2nd brought in
about 
2.1x what it cost to make.

Costs went up a bit, and I think the movie suffered a bit from a lack of 
focus. Story could have been a bit better, especially considering that it 
involved Galactus. The encounter with Galactus was rather disappointing
for 
pretty much any comic fan, (like myself) though.

So what's the word on followup installments? I've heard some rumors that 
whoever made the movies (was that Fox?) isn't interested in a followup.
Does 
this mean that the rights revert to Marvel?

The movie still made money, and I think a third one could do better with a

more focused script.

What are our chances of seing Fantastic Four 3?
