Poor Ted...he'll be the only unmarried, childless one in the group. But at least he's going to meet his future wife at the wedding, right? It'd be nice to actually have the next two seasons show THEM dating and a lead up to a wedding for them as well. It seems like the show's wandered from Ted's story for a while so I hope he gets some progress soon.
The show only has a year and a half left, and the wedding probably won't happen until at least the season finale. Or it could be next years series finale. We just don't know. I though, like you, would love to see Ted and the Mother date and then have the series finale be their wedding. He could meet her at the end of this season...
"And that kids....is how I met your mother. But that's not quite the end of the story yet..."
