It's all so very confusing.
Its a 4f jab, assuming it didn't have a frame added like a ton of his other normals (I can't imagine a 5f jab..)and the patch notes we've seen so far have all said the hit advantage on jab was increased to allow the TC to still.combo. =)
Confirmed: Ken 3f jab combo starter into target combo still works (thank god)
