Campea isn't in the leaking business, if he had a source for this "legit" image he would have had a source for years and could have leaked many things. It could just be him stirring the pot to show how easy it can be to make something look real. Sony contacting Campea, that's what he says, doesn't make it true. The images have really high contrast and look fishy.
If it turns out to be real, so be it. But this image doesn't prove anything.
Remember how it was 100% confirmed that Omega Red would be in Shang Chi and the film would be about a tournament. And people were confident that WandaVision would introduce mutants to the MCU.
