"STONE" = DLC4 (Stone=Rock)
"YELL" = DLC5 (Yell=Leader=Hilde)
"STAR" = DLC6 (Star=Seong, Hong Yun-seong)
"SNOW" = DLC7 (Snow=Setsuka)
"REPTILE" = DLC8 (Reptile=AEON)
"YELLOW" = DLC9 (Yellow=Hwang)
Almost, I think. Putting all of the referential possibilities together, I'm betting this is it:
Stone=Rock; Snow=Setsuka; Reptile=Lizardman; Star=Yun-seong (but possibly Algol); Yellow=Hwang; Yell=Li Long (but possibly Hilde)
Stone, Snow, and Reptile seem to be the most obvious calls, assuming there is not intentional misdirection at work here (which I think unlikely but cannot of course rule out altogether. I think it's probable that, popular as they are, and as much as they would bring more unique movesets to the game, the SCIV original characters are still less likely to feature, and I wonder if it can be pure coincidence that the second season pass is exactly the size you'd need to finish adding in the entirety of the SE-SCIII main roster (minus mimics, guests, playable bosses and Necrid--gawd I would laugh if 'STAR' was Necrid though, just as a prank on the community!). Interestingly, it would also mean that SCVI will end up with the exact same roster as SCIII:AE.
I'm a little surprised by the prospect that they might bundle the dao wielders together in one season, but I can't say as I'm not happy to have them both, if that proves to be the case. I just can't understand why Hilde would be 'YELL'; she's not particularly loud by SC standards, whereas Li Long does pretty consistently yell "
Hoooooooo!" at the beginning (and in the midst) of his fights; this is a variation of the concept of the "spirit shout" that is common to southern Chinese martial arts. I think he's our best bet for 'YELL' and his taking that spot, as noted above, would help close out the entire pre-SCIV main recurring roster. I think that's the plan: they get the entire "classic" cast back together by the end of Season 2, and if the serialized content proves profitable, they can do a third season that begins to tap the SCIV characters, potentially Soul Calibur V. Though honestly, if you made your third season the three SCIV/BD additions, plus a fourth guest and stopped there, it would easily be the strongest roster assembled for the franchise. Not that I won't take two seasons alone! I'm psyched just on what we've recently learned.
FYI,
@Klimat, if I'm right about the above, I think that means I'm going to win our friendly bet by 1 character. :D
