I just read an interview with executive producer Peter Lenkov, and he said that Wo Fat is definitely dead.
That bullet to the head was real, he has no twin named Lo Fat, and he will not be summoned from the dead. They truly trimmed the Fat. Flashbacks are a possibility, however, and his father will naturally become part of the story. Therefore, it is not a case of No Fat, but I would not count on his father being Hi Fat.
