I had a look, and here are my thoughts…
Absolute Zero may or may not be the same entity. The promo one looks to me to be much larger and more muscular, so I'm thinking they're two different entities.
Bunker looks to be two different entities, since I'm pretty sure the original is caucasian, and the promo one is decidedly not.
Fanatic I'm not sure about… It could be the lighting, but it's looking like there are two different skin tones and therefore two different characters.
Haka I'm also not sure about… It could be the same character, but there seems to be an enormous difference in style between them.
Legacy is obviously two different beings.
Tachyon looks to be the same character with different hairstyles and outfits. I think it's the same person.
Tempest looks to be the same being, one card looks to be at a later time after at least one difficult encounter…
Unity I could go either way on… It's possible the golems made the promo card version, or it seems plausible she did that to herself and the promo is the same character from a later time.
Wraith looks like it's probably the same character from different times in her life.
Visionary looks like it's two different characters, but it's plausible that it's the same character in two different time streams or maybe the same character after undergoing some intense hardship.
It looks to me like all the new promos are the same characters as the originals, with perhaps a different focus or at a different time.
Thoughts on any of that? I didn't miss anyone did I?
