I think Naruto should marry whom he loves and who will truly love him in return. Same goes for Sasuke. I dont think people shld marry for status and power alone, such marriages never lasts.
I think Sasuke really does love Karin(I mean he missed her heart on purpose when he was fighting Danzo!) and that they will somehow end up tougether! wease:
As for Naruto,idk....I personally think he would look cute with Ino :3
