Well, I notice that he seems to have some new gauntlet-type equipment. Could this be involved in his combos? Similar to Sektor's booster punch maybe. With that said, the small explosions we're seeing in Kano's Cybernetic variation seem to be a result of his grenades, so maybe we just haven't seen enough of his gameplay to be sure about any other upgrades he's got in store. On the other hand, maybe his increasingly upgraded cybernetics are more just a plot device to give his character bio more substance.
While we're at it though, look at this render of Kano. Look closely. I say again, can someone point out to me where his nips are!? I am a human male myself you see, and I know where nipples are usually supposed to be. Kano's got nothing there... just his rough, featureless skin.
Oh well, I guess one of his upgrades was a nip-ectomy to make him more aerodynamic. :soapbox:
