Apparently the WWE has expressed big interest bringing in two thirds of the top ROH stable known as The Kingdom. Though Adam Cole has been on the WWE's radar for the longest time there is no word of if Adam would be coming with them, but right now it seems as though just Matt Taven and Mike Bennett are on the radar. Also no word on if Maria would joining her husband and Taven in WWE, but this is also in the earliest of stages.
In an interview a few months ago Maria noted that her and Mike's contract with Ring of Honor is expiring at the end of the year which means that they will be free to chose. As of this writing I have no knowledge of Matt Taven's contract with the company other then the idea that it is likely to expire around when Bennett's does. The Kingdom in the WWE could be interesting addition to the Tag Team division as well as a good way for the WWE to add depth to a division that sorely lacking at the point. However, the only thing we can do now wait and see what happens.
