I hope this isn't the final covers, because if so then WB art dept must be lazy as all get out, something as big as Batman and they're going to give it an amature photoshop slackjob. WB covers of lately lack if they don't use the original posters.
the only way I would have believed these being the actual covers would be if they were being handled by Warner Archives (see the "general" release cover for Shazam!).
Since they're not being handled by WBA, I think we can all safely ignore these images for now. They look like they were knocked up in a hurry because they probably were. Just something to promote the big ComiCon reveal.
if they somehow do end up being the final versions, you can bet there'll be dozens of fan versions posted online for people to download.
