Interestingly, the first time I ever saw the mother on TV, she was in a Ford commercial with the Band of Horses song "The Funeral" playing. In the first episode of this season, when Ted is at the train station and we see her walking up, the same song is playing. I assume this was done on purpose, which is very cool.…

We know "everything" except the entire getting-to-know each other process. If you thought the series was going to end with him actually meeting her, you probably aren't watching the show correctly.
