The game is still three-to-four weeks out depending upon where you are in the world, but a couple extra tidbits are leaking out in anticipation of the final release of Raging Blast 2 for the PS3 and Xbox 360.

Namco-Bandai EU released a new trailer for the game showcasing much more of the game’s opening sequence, which includes the new opening vocal theme song (“Battle of Omega”) from franchise veteran Hironobu Kageyama. The trailer also showcases some new scenes from Plan to Eradicate the Super Saiyans, the included remake of the 1993/1994 Famicom/Playdia video games and OVA/guide.

The final roster also appears to have been revealed, which includes newcomers such as all three members of Coola’s Armored Squad from Dragon Ball Z Movie 5 as well as Tarble from the 2008 Jump Super Anime Tour special.

GameTrailers has a quick developer walkthrough for the game with Dennis Lee, brand manager with Namco-Bandai. A quick look is given at some fighting mechanics, but also at the “Museum” mode which houses the character profiles, voice samples, BGM collection, movies, and more.

Reports are coming in that a demo for Raging Blast 2 is popping up across some of the European PlayStation Stores (though not the Japanese or American…), so start making those extra accounts and get your download on!
