I just had a look at the raw EX frame data and here's some things I was able to make out of it.
2D is +1 on block. I didn't wanna believe it but it's official now. That move is pretty much useless for resetting pressure as it is easy as hell to IB, leaving you at -2. Good for breaking Primers, horrible for pressure. The startup and recovery are exactly the same though.
6A is exactly the same as it is on CSII.
j.B is the same as far as start-up, active, and recovery frames are concerned.
Fubuki B is 2 frames faster (15 frame start-up).
DP C is the exact same.
The air Ice Blades are all the same.
Everything else is more or less the same.
The 2D nerf was a little too much though...
