It's all just empty speculation. The only reason anyone's talking about the idea of it being used in the anniversary is because they saw photos of it being used in the docudrama and thought "Gee, I wonder if...". There's no real
reason to think there's any prospect of it happening at all. People are just desperately looking for something to fill the void of information about the anniversary episode. I'm just saying that it would be deeply unwise to take such wild conjectures at all seriously.
