Gamers have to wait just a little bit longer to get their fighting fix on 3DS.

Super Smash Bros. for the Nintendo 3DS is set to release on October 3. The game will feature many of the series' familiar features on top of the fighting, such as trophies, home run battle, online play and much more. Additional details about the 3DS version of the game will be discussed at a later date.
Sure Sells Potential says that the 3DS version is going to have more sales than the Wii U. Now I think the Wii U is going to have a much larger percentage of system owners owning the game.
