Someone at CBR heard that in World War Hulk #5 The Sentry gets killed by the Hulk.
He says:
"How creditable my rumor is. Well put it this way before they brought out the Day Of Vengeance book ( DC Comic ). I stated on the DC Comic forum that I heard rumors that the Wizard Shazam will die and 5 months later it was true. But conveniently I can not find the link. These rumors are from the same source I'm hearing it from."
I doubt this is going to happen, epecially the bit about Hulk returning to his planet afterwards???
I can't see them putting the work into Sentry that they have, building him up to be the most powerful hero ever only to kill him off during an event.
Sentry is going to play a big part in ending World War Hulk imo, Hulk has already shown signs of compassion and with Sentry's ability to calm him, he may see the error of his ways (after of course one huge fight with lots of property damage).
Ultimately Hulk's crusade has to fail, someone has to bring it to an end and with Black Bolt and Strange both failing, Sentry or Thor are the only other two characters with a shot at it.
honestly, what the **** man? why does this matter so much to you? it's a COMIC BOOK? it's for entertainment purposes? why are you making such a huge deal about the the shade of an echo of a concept?
It'll end spectacularly however , considering a bunch of Aliens from the 51st Century travel back in time to record the events of 'Hulks war on the Super-Heroes'.
