I dont really understand why anyone thought we'd get something yesterday. With an episode tie in, they have never given us something on the day or after the episode.
The closest was the Halloween 2012 where there was a question asked before the episode about the episode itself. They have also sometimes given something to tie into the events, like on Xmas day, Valentines day etc and then there was the superbowl give away.
But never when they have had a standard episode tie in have they gone on to give us something post episode. So I dont really understand why people thought they would. They always do the question in white text in the balck box at the end of an episode tie in, saying watch on Sunday to find out. Its just promoting the episode.
