I don't know if you remember, but I posted a poll back in April regarding how continuity between TW and DW was important. 41% of the people who responded thought that 'BBC is in for a smackdown if they ruin this'.

I had foreseen that when people saw the spoilery bit revealed in the clip we would see these types of discussions in this community. I am beginning to wonder if we had the same type of poll it might reveal the same results!
