Well... Rise of the Ninja is exclusive to Xbox, just like Clash of the Ninja is to Nintendo.

The Ultimate Ninja series are the exclusive one for the Sony systems... and as you can notice... the 3 series are done by different companies. CyberConnect2 is a personal favorite of mine thanks to the hack series.

One thing about the supposed 25 characters...

If the game follows the story all the way to the Sasuke retrieval arc... which characters are cut out? We have 15 'rookies' (Kakashi's team, Asuma's Team, Kurenai's Team and the Sand Team), Kakashi, the 3 sannin, the Sound Five, Kabuto, Sandaime, Zabuza, Haku, Itachi and Kisame... thats 30 characters... if those with not important battles are cut out... then who gets out?... Tenten? Ino? Shino? Kankurou? I hope the download rumor is right... but that its cheap as well.
