There's nothing wrong with an ambiguous ending inherently. There's plenty of theories as to what happened with Raynor and Kerrigan - that's kind of the point. The dev pretty much confirms it's meant to be ambiguous anyway.

But whatever the case, Raynor and Kerrigan's story is over. It doesn't need to be dredged up in a sequel.
