With all these strings that seem really reminiscent of MKX strings, hopefully the frame data isn't garbage again so he can have a serviacble stagger. I didn't see an overhead starter outside of F3 but maybe I'm just blind. Perhaps they decided to make him a stronger neutral character instead of a mix machine this time around.
There are some buttons to reveal yet so he could still have an OH (though I don't think his MKX B2 is coming back, but probably some of his MK9 overheads are back).
We got:
s1: The same as in MKX leading to 111, 112 and 123.
b1?: Which will use his B33 animation from MKX.
f2?: Which will use his F33 animation from MKX.
s3?: He has a couple of kicks that doesn't seem to be related to any of his known animations, I'm guessing it will be his 3.
F3: What used to be his Cryomancer hammer is now his OH bounce (yay! I called it!).
B3: What used to be his MK9 B2 is now his wall bounce.
The returning F122 Cryomancer launcher could either be s2 or f1.
B2 is probably the best bet for a possible OH starter. Many characters don't have the full set of directions for 1 or 2 but depending on which button got the F122 string from MKX there is still room. He sure has a lot of lows (B33, F33 and 123 from MKX are all back in addition to his slide and Supermove) so it would be a pity if there wasn't an OH to mix them.
EDIT: I forgot that F42Throw is coming back too, That will probably be his F2 and his old F33 will probably be his F1. What used to be his Cryomancer F122 is almost sure his s2, so we only have S2 as a possible option for OH starting combo.
