As a part of what appears to be called the “Sparking Campaign” with eight new cards, new updates for Dragon Ball Heroes (the Japanese card-based arcade game follow-up to prior Bakuretsu Impact and Dragon Battlers games) will include a new Super Saiyan 3 transformation for Gogeta, the fusion dance combination of Son Goku and Vegeta originally seen in Dragon Ball Z Movie 12:
Three exclusive cards featuring Super Saiyan 3 Gotenks, Goku, and Vegeta will be included with the August issue of V-Jump, which hits Japanese shelves today (21 June 2012):
All of this is tied in with the “Galaxy Mission 3” update coming to Dragon Ball Heroes, which also includes some Dragon Ball GT action:
The first Super Saiyan 3 forms debuted in a video game (where it was not originally debuted in the original manga series or theatrical films) were for both Broli and Vegeta for Dragon Battlers back in 2009 — both of these Super Saiyan 3 forms appeared in the first Raging Blast as playable characters, as well.
Super Saiyan 3 Trunks made his debut in Dragon Ball Heroes a little over a year ago, but has not popped up as a playable character in any traditional console games.
