Here's an obvious question; since the anime and manga series ended abruptly, who does Ranma end up with?
Since won't know what will actually happen in the future, its anyone's guess, but lets try to remember the concepts of Ranma's fiancees.
It is highly possible that Ranma will end up with Akane mostly due to her being the lead female(or second lead if you count Ranko) of the series and that the series itself focuses on Ranma and Akane's progressing relationship as it starts out as a "shy friendship"(when Akane thought Ranma was a girl) to bitterness(after Akane discovers his secret and stating that she hates boys) which eventually becomes a love-hate relationship. Now we must remember that their oafish fathers, Genma and Soun, had made an arangement to have Ranma and one of Soun's daughters(Kasumi, Nabiki and Akane) to marry and carry on the Tendo dojo, so Akane was technically Ranma's first fiancee, however she was last of his fiancees he met. Ranma and Akane had flaws that each hated about each other; Akane does not like his insensitive and prideful attitude as well as constantly teasing her about her physical appearance( saying that she under developed compared to most other girls i.e. "smaller chest, bigger hips) while Ranma does not like her tomboyish personality(often refering to her as "un-cute" and a bit manish) and how she often attacks him as well as her going into violent outbursts. It was already clear that the two do not want to get married especially to each other, mostly due to them feeling that their emotionally ready for such a thing and because it was an "arranged marriage" and no one likes that.
For Shampoo, Ranma can barely stand her or at least her annoying obssession to marry him. Now before the marriage thing happened, Ranma defeated Shampoo as a girl and(due to the Amazon's strict rules) she had to hunt female Ranma and kill her, but after tracking him down in Japan and being defeated by male Ranma, she immediately fell in love with him and tries endlessly to get him to marry her. Ranma, on the other hand, did not feel the same way for her as he was not looking for a wife, especially one who tried to kill him. In his mind at first, "It's bad enough I have one tomboyish fiancee, but I don't want another crazy one." Throughout the series, Shampoo has made many tricky and underhanded attempts to force or convince Ranma to marry her and move to China with her and her family. Ranma has stated outright that he thinks of her as pest, but does seem to care a great deal for her(in a good friend or close comrade kind of way) plus he actually thinks is cuter or more attractive than his other fiancees(when she is not on killing rampage).
And with Ukyo, she and Ranma were childhood friends and she was the first his fiancees he met(though he had no idea that she was really a girl). She became his fiancee after his stupid father accepted the dowry Ukyo's father offered for the two to be engaged only to leave her behind. After that Ukyo swore that she find them and make them keep their promise. Even after discovering that Ranma has two more fiancees, it did not stop Ukyo from trying to marry him, not only because she loves him, but for her to restore reputation as a woman or a bride and will not stop her rivals have stopped. Other than marriage, she was okay with just dating Ranma until he was fully ready to get married. Ukyo was the only fiancee Ranma can tolerate and even referring to her as his "cute fiancee" only due to them being childhood friends and in a way already treat each other like family.
So, if the future were to be seen or predicted, what would you predict? Would he marry Akane? Shampoo? Ukyo? Or all three? Or is there someone else in mind?
