I'm not too worried about all this news. Even if Affleck isn't able to be in the suit, it doesn't mean he has to be completely out from the upcoming Reeves film. Heck, he could retire and help train his successor ala Batman Beyond, and still play Bruce Wayne as a mentor figure.
Plus, to be honest I'm not sure if THR has a bias against the DCEU. I still remember that report about Suicide Squad's production problems conveniently coming before the reviews and opening weekend. This feels like yet another thing to take advantage of us worrisome fans.
