I don't think Grey's Anatomy will have an ending with ghosts, because they did ghosts in season 5 with Denny (although that was later explained to be tumor hallucinations), but critical acclaim was all negative. So I don't think they'll want to pull of an actual ghost storyline. Or they could decide to do some sort of afterlife thing again, where a character whose life is in jeopardy (probably Meredith) meets her deceased friends in the afterlife.
