I think that pretty much sums that up. They are not ending the show despite killing off virtually the entire cast. Gotta hand it to the BBC it takes a lot for them to consider cancelling a show, not like ITV. One can only wonder how they can continue the show now though. Oh by the way, spoiler warning. :)
