Fleet Admiral
I think they are just referencing the fact that they are getting a guest star known from Doctor Who.
I seriously doubt they will do any kind of crossover... especially only 4 episodes in.
But that kind of ambiguous language is a clever way to try and generate buzz and awareness.
My own instinct would be much the same; I think however the language in the announcement is not clever but rather a bit sensationalist for the sake of attracting people to the release, which is fine I guess, but somewhat irresponsible as it (casting actors from one in the other) has already been done. Your mileage may vary.
