The Edge and Christian Show wrapped season one with the finale airing last night on the WWE Network. According to a report attributed to PWInsider, there are no immediate plans for a second season.
Christian was just recently released from his WWE Performer’s Contract, having to retire due to injuries. I would imagine WWE will want to work with him and Edge in another capacity if the details can be worked out. Original programming is seen as second to only the live pay-per-views and special events that are driving the growth of the WWE Network and are obviously a priority for the company.
