Wow, that's ... not original (see Fantastic Four 381 October 1993). Kind of sad that the only way Marvel can think of to generate interest in their titles is to "kill" someone, but it's just plain funny that the mass media pays any attention to "news" like this.
I voted for The Thing because they already "killed" Reed once & doing it again would be too lame, and I can't see the "death" of Sue or Torch having an effect that will "will ripple across the Marvel Universe like never before". How would The Thing's death affect the Marvel Universe? I don't know, but he's the only one of the four that was popular enough to get his own cartoon series, plus a long run in Marvel Two-In-One, a 36-issue series in the 1980s and another series in 2006. My point of view is that, for better or worse, comic fans would actually care that The Thing was killed, whereas the other three would just get a "yeah, so what?" response.
On the other hand (and I should have thought about this before voting), killing The Human Torch makes more sense since Marvel seems willing to use their stable of Golden Age characters, so why have two characters that are, for all intents & purposes, exactly the same?
