It has been confirmed that the mysterious ne dragon ball game being made by Namco Banda is indeed Dragon Ball Xenoverse. For those who do not know it Xenoverse has you avatar repairing the time line of Dragon Ball Z after it was altered by Mira. The avatar can be of any race with Saiyans only allowed to go up to level 3.
This time around things are being altered but the trailer seems to hint that the alteration are being made for the good side as things they wish to change. When protecting time it means as it and nothing can be altered.
As always thank you for reading.
