Since his wedding to Maryse Ouellet is taking place later on this month, there is a very good chance that the current story line for the Miz is a way to write him off of television. Though he hasn't been penciled in for a match at Wrestlemania 30 yet, he's expected to return by then.
When WWE previously asked her about a return to the company, Maryse Ouellet turned them down, as she was busy working on some projects and preparing for her wedding with the Miz. The belief, though, is that the company will try to offer her a contract again after the wedding in February.
After TNA Lockdown 2014, Seiya Sanada is sticking around and working a couple of episodes of Impact Wrestling. The belief is that Dixie Carter and company will be giving him a nice push, as management wants to maintain a good business relationship with the Great Muta and Wrestle-1. They also want to entice other Japanese stars to come tour with them.
