Fighting games have been appearing on the 3DS ever since it's launch date. Fighters such as Super Street Fighter 4, Dead or Alive Dimensions, and BlazBlue Continumn Shift II released within 3 months since the 3DS' launch which might set a record on consecutive fighters launching on a console. Tekken was confirmed for the 3DS at E3 of this year which will add to the list of many fighters on the 3DS. It wouldn't suprise me if games like Soul Calibur and Mortal Kombat started appearing on the 3DS since a lot of fighters are releasing on the console. Perhaps we'll see many more coming by the end of this year.
