I just hope they're looking at NGBC Kyo for inspiration for NESTS Kyo. Primarily, I hope his new Dokugami chain (which ended with an explosion and allowed for follow-ups) is his EX rekka move, and I hope he gets an aerial R.E.D. kick (which would re-use the same animation anyway, and give him more combo potential). Other than that, I just hope they get as many of his dokugami variations as possible.
Of course he'll have Orochinagi. Hopefully he'll regain the ability to charge it, and I assume he'd lose the aerial Orochinagi. Don't think it fits him as well.
For a second DM, this may sound odd, but I'd love it if they just spiced up Kototsuki (his run-and-grab move) and used that. Kyo-2's MAX2 was basically a really flashy kototsuki and I thought it looked great. The EX version could function like his grab MAX2. So just like normal Kyo has normal version with the EX version being a command grab, NESTS Kyo could have a DM version with the EX DM version being a command grab. I dunno. Call me crazy if you must!
His NeoMax should be something short, powerful and representative of the character. Just like normal Kyo's NM is "just" a projectile with an awesome follow-up, I'd want NESTS Kyo to "just" throw a punch (maybe even the same as his qcfx2+P DM) with a cool, explosive follow-up.
