Hmm... ok, you've got a point there. Yet, I'd still say to the average first-time-viewer this won't be anything more than a hint. In my book that line doesn't blatantly give it away. It is more revealing than the old dialogue though.

To be honest I still would have preferred if they just had put Ian McDiarmid in there without changing any dialogue at all. There really was no need to hint at this some more. Oh well, we'll have to wait and watch it to be sure how it'll come across I suppose.
