I have faith that Ben will appear in Ultimate FF eventually. Fialkov brought him back during his Ultimates run after every previous writer had forgotten about him for over two years.
If the writing was this good and consistent in all the ultimate line it would be doing a lot better. Also stop killing off all the good characters just for shock value.
Wonder which Doom was the one that died by Ben's hand..
Sue is going to snap when she finds out that Ben had killed "Doom"... At least there's always Namor who does seem to want to treat her right even if he's kinda stubborn and hardheaded.
