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.
Miz and Maryse Ouellet are really trying to build a life together. Aside from getting married in the Bahamas in February, the couple also has been looking for a house to purchase. Since Miz has been on the road with WWE, his fiancee has been in charge of finding them a new home.
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.
