I'm sorry, but I must quibble with .2% of these deaths. [Spoilers...DURR]

First, watch the video from the folks at Digg. Then I'll begin my little fan-rant.

Wait for it.

OK. Sansa and Reek/Theon are not dead! Yes, they jumped off the same wall that Myranda fell to her death from, but with a major difference: Myranda fell (well, belly-flopped) onto the cleanly-swept stone floor of Winterfell, whereas Sansa and Reek/Theon jumped outside the wall. We've seen Winterfell receive snowfall in literally every episode this season. Combined with winds, we have every reason to think there is a significant snowpack at the bottom of that (admittedly high) wall.
