I think this will be the case as well. I still maintain the conviction that a BD version of Armored Bats is in the future and I base that on the lack of a spear accessory with any of the current figures. I think it's being saved for a BD Armored Bats, which I also think will include a diorama base with rubble to make the figure more enticing to collectors and differentiate it even further from the regular Armored Bats.
I know someone mentioned that none of the AoU figures came with Loki's scepter as an accessory even though it was a main part of the film, so therefore, the lack of a spear isn't really a good clue to go by to speculate a BD Armored Bats is in the future. However, regarding Loki's scepter, there were already a couple of A1 figures that came with the scepter, so there is a scepter accessory out there in circulation. The Kryptonite spear to me seems too vital of a component in the film to not be included at least once with any BvS figure.
I think of it like Apple, or any tech giant. Whenever Apple comes out with a new iPhone, they generally only have a slight upgrade from the previous iPhone, especially when it's an S version. You can't tell me that whatever the slight upgrade was, that they didn't have the wherewithal to include that particular piece of tech in the current iPhone; they're saving it for the next device to give people an incentive to purchase that one. No need to include it now, because they'll get it in the next one.
In fact, I said in another thread that I could see HT doing both a SS Batman and JL Batman, but it wouldn't surprise me if they possibly forego doing a SS Batman and release this in its place and use the presumed popularity of the film and the fact that Batman is in it, to push sales for a BD Armored Bats. Or they make both, knowing that people will probably buy both.
