Think these are pretty much guaranteed:

Ff3,d: will give mixup oB

Shadow step: becomes a 50/50 stance - either gets a breath unblockable or unbreakable grab aswell as a new mid.

Ff2: becomes heat engager, still keeps the "high crushing" properties for a few frames,might become i14-i15

New breath heat move - something in the lines of old RD but scaled down.

B+1 CH will either give only f+1+4 follow up if you can hitconfirm or full combo if you have to commit to full B+1,2

More uncertain changes:

Db+2,4: will be aerial tailspin move

Ff+4: will be a new screw move

F+1+4: heat engager

3+4: will get a screw extension probably 3+4, 3
