What have you noticed that you can do in 2012 that hasn't been documented already?
Ryu can do 3 ex fireballs and follow up with ultra (i think its counter hit only but I'm not sure)
Viper
Can combo 4 burn kicks after seismo (regular H.bk, ex iabk ex iabk ex iabk)
Can combo an EX Burning Kick into 2 more EX Burning Kicks
Can combo U1 after landing EX Burning Kick mid screen
EX Thunder Knuckle can be used an anti-air.
Adon can AA with super, just end it with the kicks. Also m.jk feels different in the spacing.
EX jaguar tooth combos into ultra 1 for hard knockdown.
Ibuki
U2 Combos with EX Tsumuji in corner
U1/U2 can combo after cl.st.HK
Counter hit Bansho Kick combos into either LK/EX Kazegiri, Target Combo 4, Target Combo 6, and Target Combo 9
With dudley, if you do a focus attack and it hits, dont dash and let the opponent crumple. Do ultra 1, and you can juggle after that.
All I got for now, I'll find some more as time goes by.
