I'm pretty sure Kano loses to Shang now if he didn't already. Unfortunately I have yet to play a good one so this is just theory fighter, but that new EX soul steal takes away Shang's biggest weakness here.
On the flip side, being able to land real combos on Cyber Sub's parry is nice! If anything Kano may win this now - you can't throw knives but your pokes and frametraps destroy his, and parry is a much riskier way out than it used to be.
Liu Kang is somewhat similar to the above, except I'm more sure of Kano having an advantage. The main difference from CSZ is that he has no easy answer to knives without meter. Also, this is one of the matchups where Kano getting a real armor move matters most - Kang's f+12 is one of the strongest frametraps in the game and in my experience you can't even upball another f+12.
I definitely feel like he loses to Mileena, even after learning the match a lot more since Summer Jam. Good players can telekick knives and jumpins on reaction, and roll is an even easier AA. This is not good considering you don't have much of an answer to d+4 besides jumpkick xx airthrow...I've tried spacing her out and using f+3 but nope, none of Kano's strings work. Armor is pretty meaningless here, so I think this is still 4-6.
The Cage matchup improved but probably just by .5 - the f+32 nerf for him and the armor ball for you are both factors here. Again, Cage gets so much advantage from some of his strings that Kano had no options besides blocking before.
I feel strongly that even prior to this patch the Kung Lao matchup was 4-6 at worst. You own KL real, real bad in footsies - walk back to bait strings then punish with b+112, or f3b2 if you see him dashing in, etc. The main adjustment you'll have to make with good players is dealing with whiffed divekicks, but you can dash block for a big punish if you feel that out. There's also the fact that he can't spin out of f+11 frametraps. With the new patch, this is 4.5-5.5 or possibly even.
There's no way Nightwolf is 4-6, considering his only normal that outranges yours is the slow-as-hell b+2. His pressure on block is almost nonexistent, and he needs to burn meter to get out of yours. All of NW's great anti-zoning tools are a non-factor here since you want to hang out at mid-range. That said, he does quite a bit more damage than you and has a fantastic whiff punish with shoulder. This seems around even to me.
I have to imagine Cyrax will be in Kano's favor now. You can air ball bombs/nets on reaction, your pokes are better, and he has problems breaking out of pressure. This is another matchup where I hardly throw knives btw.
6-4 on Kitana seems about right to me, especially now. This is another matchup I've learned a lot about since Summer Jam, and I would love another crack at it. Knives are a threat to her iAF's, and you can ball on reaction if you see her go higher in the air.
Noob is an interesting one, as I'm not too sure if all his changes will affect this match much at all. Your main strengths here are (again) pokes/pressure and being able to air ball his projectiles on reaction, and none of that has changed.
Smoke ain't a 4-6. Again, it seems like people still think of Kano as a zoning character when he's really a mid-range one. Shake and smoke bomb don't make his normals faster or give them more range, so I don't see what the problem is. This strikes me as slight advantage for Kano if anything.
On the opposite end, no way is Scorpion a 6-4. Hellfire is better at stopping your approach than NW's lightning since it's faster, and spear is an awesome whiff punish. Semi-random EX teleport is also a very strong weapon against your poke game. Scorpion's buffs are also more significant than Kano's overall, particularly having a real wakeup move. I'm thinking 5-5 now.
Reptile was one of the matchups where knives mattered most, as they were your main answer to his whiffed elbow dash movement, and the patch put a big dent in that. I actually think Kano might have won this before, but no way now. Thinking 4.5-5.5...
Kano should still beat Sonya, but I'm not sure how much of a difference the EX cartwheel makes.
Raiden is definitely not even lol. He easily out-lames you, and you can't punish teleports since you don't have a divekick or a fast jab. You can't effectively pressure him on wakeup, which is a problem when all of your combos knock down. Furthermore, he's one of the few characters who convincingly outpokes you thanks to b+312, and superman is an obvious whiff punish from farther away. 4-6 at best, and only Sub is worse IMO.
Finally, Sub-Zero. EX slide. 3.5-6.5. To quote the immortal Skip Rogers, "HAPPY GAMING!"
