I think they may have rolled out Hogey as a teaser for possible future appearances. Twitter last night and today has been abuzz with people mentioning Hogey. I myself was on the phone to Sky earlier, and I told the agent in a Spanish accent that she 'keeled my brother,' so the little guy has had an effect on me already. The reaction to the introduction of characters like Dwayne Dibbley and Ace Rimmer caused the same kind of stir pre-internet times, and they were brought back to greater or lesser effect, depending on your point of view. I'd like to see Hogey back, but whether they can find a good character arc for him and rid him of his obsession to duel his nemeses across time and space is another thing.
