yes it is just a port of the two thrones from last year. it has been retitled rival swords. they get away with the new title by saying that it is 'based on'.
here is a extract from the prince of persia website
"Rival Swords will ship March 2007 for the Wii™. Based on last year’s highly successful Prince of Persia® The Two Thrones, the game takes advantage of the revolutionary Wii remote and Nunchuck. Players will be able to clash swords with enemies, execute speed kills and perform the Prince’s well-known acrobatic moves such as running on walls. Prince of Persia Rival Swords creates an epic experience by combining two playable characters in a masterly balanced gameplay, with the perfect mix of combat, platforming, puzzles and a compelling storyline."
