There were a lot of things like that lined up like that, Jordan really planned long term in his books (or at least had a lot of help).
But then there are so many things that weren't talked about.
1) Elayne's kids (we didn't even get names),
2) Aviehndia's kids,
3) the whole Seanchan taking over the world bit,
4) Almost nothing about Lan/Nyn and Malkier,
5) the Perrin/Faile kingdom thing was only really hinted at,
6) Oliver and the Horn,
7) Galad and her Lady First,
8) Tom was pretty much ignored at the end (for shame)
9) The whole Black Tower was kinda just thrown under the rug
10) Where is the Red Ajah going..
The list goes on... They spent several chapters or at least emphasized in several scenes at least some of these characters/organizations and then just didn't even address them in the Epilogue... I was kinda disappointed in that chapter.
