Mark Millar Plural Hulks Reference

So lots of people are chattering about a bomb Mark Millar dropped on his forum prior to leaving on vacation, regarding the next Crisis/Wars event at Marvel:

It involves a symbiote at one stage in the story, the death of the greatest Marvel hero, a new President, a blind superhero driving a car 3000 miles and The Hulk as you've never seen them (yes them) before. It's a lot of fun and I have a feeling this is going to be MASSIVE.

With World War Hulk as yet unresolved, it seems possible that Marvel will break the Hulk down into multiple personalities again or even into multiple bodies (again). Obviously the She-Hulk is a "hulk", so she may count as one of "them".

I wonder who the dead "greatest Marvel hero" is meant to be? They've already killed Captain America, Spider-Man died last year in the run-up to Civil War and then came back, Thor just came back from the dead, Captain Marvel just came back from the dead, and the Sentry has hardly been around long enough for his death to mean much. The only one left who might qualify is Ben Grimm, the Thing, who during the 80s (but not much since) was often depicted as the most committed Marvel hero, with the greatest heart and most integrity. So it's hard to say.
