So this hasn't been confirmed by anyone as far as I know, BUT...The new Batman movie starring Robert Pattinson MIGHT be the start of a "new" DCEU depending on how well it does. One that will eventually phase out the current one:

Found this on the Superman thread and have NO IDEA how reliable this guy is as a source, but I don't think it's a surprise that the new Batman will have no connection to the current DCEU. If anyone knows more about this than I, please feel free to share.
