Tekken 8 will get a new update soon which will change a number of things about the game including some fixes around some characters' moves along with some bugs which have been resolved.
However, the biggest announcement is that there will be an in-game shop for Tekken 8.
Details on what will be available in the shop is currently unknown, but it is expected that players will be able to purchase cosmetic items and maybe even skins which they can use on their characters.
This is somewhat new as Tekken 7 didn't have an in-game shop and it has raised fears that this could be a means of conducting microtransactions.
