...the point of item #4 was this part: "...that they can't seem to nail down the scope, focus, or timing of in relation to setting up the Justice League film."
But the operative word there is "seem." It would be a huge mistake to assume that the lack of clarity in what's been
made public to date represents a lack of clarity in the actual planning. What we see is just the tip of the iceberg. Heck, it's just the barest glimpse of the iceberg peering over the horizon. For all we know, they may have a very clear, detailed plan for their films; but we're just learning about it in dribs and drabs, through secondhand sources and rumors and leaks and speculations. So what we're aware of is bound to be a whole lot vaguer and more confused than what's actually being done behind the scenes.
