Reading the article again I do not believe it is anything but click bait. Both site and author are suspect in the extreme. Plus none of it makes sense. Warner has a settled plan for the heirs and D.C. will never-ever- retire and move on from Superman. Like some of the others out this is not the first time the the author has made unfounded claims along with the reasons why he does it.
They will be making some Superman fans upset if they do indeed reboot Supes as a Black version now, so compound and fan the flames still further by now making him gay?
