=In the most recent Jump manga, it was mentioned that Jump Superstars, a new game for the Nintendo DS, will soon be announced.
Rumors have been swirling around Japan that Nintendo will be the one developing said game, using an engine similar to the one used Smash Bros. games. The timing of the announcement comes very close to Nintendo's October 7th press unveiling of more DS specifics, so it seems likely that we could see more of the game there too.
Jump and its publisher Shueisha carry a very large amount of popular manga IP. Anime fans may note such titles as The Prince of Tennis, Naruto and Hunter X Hunter, but even those who don't follow anime may recognize names like Dragon Ball and Yu-Gi-Oh, which were once featured in the popular manga magazine and are obvious sources for character choices. One Piece, the manga about pirates that recently started airing on North American television, as well as Shaman King and Yu Yu Hakusho are also Jump properties and likely to be featured somewhere in the game. The treatment will likely be similar to last year's Konami/Hudson/Takara all-star bash.
Whether it's being developed by Nintendo or not, or is in the style of a Smash Bros.-like fighter, the game is much more likely to see translation than most anime-based games that are released in Japan. Anime fans who are looking forward to the DS may be in for a treat in the near future.
