Nelson's revealed moves look interesting. They might showcase a number of properties that are updated for this game. Two of his attacks slam terry to the ground potentially ground bouncing (probably only one will if either) and his last shown move before the dynamic camera sequence does a wall slam (I'm guessing this is a super). He also has what appears to be a teleport type move.
Athena still has a magical skirt, not only does it never reveal the underside it now allows her legs to pass through it, I'm guessing it's breathable lol (to be fair though, clipping hasn't been that big of a problem in this game, just a few here or there, so far). And that spirit bomb mostly looks like what she did in her XIII Neomax sans goddesses.
Luong's Frankensteiner makes me worried for Clark's. Other than that she seems to have a fast kick special like beni's (but we haven't seen if it has a follow up), she's got an overhead normal (her backflip super might be overhead as well), a move which is probably either a counter or stance (I believe it's a counter), and what appears to be a ranbu style move ending in her dancing on her opponents face. Looks fun.
I can't wait for some of that KSB footage. With 20 characters at that build, I hope we get to see some grapplers, and more Max mode so I we can figure it out more.
EDIT: just realized Luong's stance is probably that fast kick special (making it like Yama's serpent slashes but with feet), she goes into that stance before shooting her foot out each of the other times it's shown in the vid (her first combo, and her super cancel) I didn't even realize how far her foot shot out til I watched her section again.
