There is a strong chance we have the wordpress theme done within this year. We have already discussed it, started it, but are currently focusing on XF 2 specific add-ons and themes. Early 2018 is possible, if you were to fund the project we would be able to expedite it. Feel free to create a ticket at themehouse.com if you are interested.
At the moment there is no update on a WordPress theme. We do not plan to start seriously developing a WordPress bridge theme until we are completely finished with all features of UI.X 2 Pro, which will hopefully be before the end of the year. We will keep you updated as time goes on
If you don't want to wait for "official" theme you can achieve "almost" identical look with this Wordpress theme: https://wordpress.org/themes/generatepress/ but you need to know some CSS to make it look similar to your Xenforo.
