It'll be like later KOF games (but not the Eolith ones cuz they changed the hitbehavior and make it look really weird and dumb looking). The instant knockdown always looked weird to me.
But the most important gameplay change (to me) will be this goddamn animation:
in KOF, Benimaru holds his hands outstretched for a fairly long time, giving the attack a lot of emphasis and power. But he goes back to idle too fast in CvS! Finally this horrible mistake will be rectified. >:[
here's a tentative movelist:
<NORMAL>
.Jackknife Kick F + b
.Flying Drill D + c (Air)
.Front Suplex F/B + 2p (near opponent)
.Catch and Shoot F/B + 2k (near opponent)
.Spinning Knee Drop: F/B + 2p (Air, near opponent)
<SPECIAL>
.Raijinken (EX) D, DF, F, p (Air Also)
.Taiku Raijinken (EX) F, D, DF, p
.Iaigeri (EX) D, DF, F, k
.Hando Sandangeri D, U, k
.Super Inazuma Kick (EX) F, D, DF, k
.Shinku Katategoma (EX) D, DB, B, k
.Benimaru Collider (EX) F, DF, D, DB, B, F, p (near opponent)
<SUPER>
.Raikoken (MAX) D, DF, F, D, DF, F, p
.Denei Spark (MAX) D, DF, F, D, DF, F, k
.Elec-Trigger (MAX) F, DF, D, DB, B, F, DF, D, DB, B, p (near opponent)
which isn't really full of surprises, I suppose; he already has basically every important move of his in CvS2. He's getting the aerial version of Raijinken, though.
level three will either be the HSDM from 2002UM, or his Neomax from XIII. Both can be pulled off pretty easily with existing sprites, but they both feel pretty eh to me, so much so that I'm still undecided 3 or 4 years after I first started thinking about doing Benimaru! But right now I'm probably leaning more towards the Neomax; it might be boring and lazy, but it at least has some oomf. Though I guess the HSDM could have weird/fun combo potential...
