In the long-running "Dragon Ball" universe, the arcade game "Dragon Ball Heroes" can be considered old. The title, the sixth in the franchise's "Dragon Ball Carddass" trading cards type of play, was released way back in November 2010. 

However, the game keeps updating as new content surfaces in the "Dragon Ball" universe. Most recently, game developer Bandai Namco unveiled a new "Dragon Ball Heroes" trailer, which hints at a new character transformation expected to take place in the new "Dragon Ball Z" movie. 

In the video, Son Goku, the main protagonist in the series, is shown enveloped in a golden aura quite different from what usually appears when he powes up. A new wave of energy seems to spring forth, and Goku's new transformation is about to be revealed but then, the trailer cuts to the date when the movie will be released in Japan. 

The movie, "Dragon Ball Z: Fukkatsu No 'F'," will be shown on April 18. It revolves around two new villains, Sorbet and Pilaf, attempting to resurrect their leader Frieza using the Dragon Balls. Frieza gets an almost-god like upgrade in the movie, and travels to Earth to battle Goku and the Z warriors once again. 

It has been rumoured that in this new movie, Vegeta will become a Super Saiyan God, which first happened to Goku in the previous "Battle of the Gods" movie. 

The upcoming film will also be shown in the United States as "Dragon Ball Z: Resurrection 'F'" and will be a dubbed release. No specific date has been announced, but fans of the series can catch it early at a special premiere to be held in California. In this, maker Funimation Studios teamed up with 20th Century Fox and Toei Animation for the special screening. It will be held on April 11 at the Egyptian Theatre in Los Angeles, California.
