Amazon in Germany have listed this very interesting listing for a First Edition Star Wars Black Series Sith Trooper in white packaging.
The First Edition wording has only been used once before, on the debut wave of the Black Series back in 2013. The white packaging is of course also new.
If accurate, this is the third packaged version of the Sith Trooper following the SDCC exclusive and the regular packaging (spoilers in link).
It also seems an odd choice of words to call this First Edition as the regular packaging is already on sale in Disney stores in the US?
The First Edition white boxed Sith Trooper is a pre-order and will release on Triple Force Friday, 4th October 2019. UK collectors can order this directly from Amazon Germany at circa £28 delivered. There will be no custom charges as we are still in the EU (at this point).
