This is my first time actually starting a thread here, I stick to Giant Bomb because arguing about superheroes scares me! Anyway, with the announcement of the "Future Foundation" and the new comic series, how long do you expect this to last? It seems mad to kill off the Fantastic Four just like that and start anew but maybe it was for the best? 
 
What're your thoughts?     
 
Also, does this basically mean they're Marvel's JLA?

hopefully when they go back to being the fantastic four the other members won't just dissapear in to limbo

Until 2012's "Fall of the Future Foundation" Story arc.

13 months. I'm betting it here and now. 
 

As long as sales are up for this comic, after this there just won't be any FF for a while and then they return with the resurrection of Johnny Storm.

I think it will last a little while. There has been speculation, based on what Marvel tends to do with every popular book, that it will go until they can claim a Fantastic Four #600. So that would be less than a year. 

How long does anything last in the Marvel Universe?  At most a year until the "next big crisis cross-over that will change everything!" ™  
 
By the way, this whole thing familiar to anyone?  A scientific organization of the greatest human minds promoting a better future through technology, wearing white and black uniforms with hexagonal logos?  I think the boys at Marvel have been playing a little too much Mass Effect 2.
