A few minutes ago, we posted on Kakuzu, Deidara, Sage Jiraiya being confirmed in Naruto: Ultimate Ninja Impact. We also posted the box arts for the Japanese, North American, and European regions as a comparison in that post. As it turns out, the Japanese box art, which differs a bit from the North American and European versions, also shows Sasori, Hidan, Konan, and Shikamaru! Thanks to michaels for point it out!
