The WW version, I personally wouldn't hold my breath on. I can't give you a reason, but I honestly just don't see it being made, at least not any time soon. The JL version I think will essentially be the same as the BvS version, just a newly fabricated and likely improved sculpt, and perhaps some minor tweaks to the outfit and the sword and shield (die-cast perhaps?). I don't really see what kind of improvements they can make to the actual body itself.
I have the BvS version and simply plan on just potentially picking up a parted out JL sculpt to put on it, provided there isn't a noticeable different in skin tone, which I don't imagine there to be.
