We got images of early production test shots for some Transformers figures lately and one popped up of Tarn's body with no head and a new sword, on
Chinese social media. This has fueled the idea that this is Legacy Bludgeon's test shot. Now it is unclear if this is a work in progress type test shot or a pre production line one, meaning that we don't know if this represents the amount of retooling Bludgeon will have over Tarn but there is now a possibility that this indicates the retooling could be very very limited. Basically, it could be that Bludgeon is just the same mold as Tarn but with a new head and a new sword accessory.
While that is not what fans were expecting, it does explain several elements in Tarn's sculpt that are more akin to Bludgeon than Tarn like the plates on his thigs, the eye holes on the upper chest and the vent at the centre of his chest, just to name a few.
Of course, it could also mean nothing, so we'll wait for more info.
