Anyone else knows who the mother is?

I just rewatched HIMYM and now realised i know who the mother is. Or at least who they wanted her to be. Probably gonna ghance her now. In season 3, episode 12 - No tomorrow ; Barney and Ted went to a party. At 13:25 Ted bumps into an anonymus lady, says he's sorry, the girl says don't worry and that lady never appears in the tvshow(remember that's the episode where he says that he was in the same club with her on the same night). In movies people never bump into each other in the disco with the main character unless they have something to add to the story. That's Ted's Wife. Does anyone agree with me on that? Haaa Gotcha!!!! Hope they don't change her, i saw the scene a couple of times and she's so hot.
