Do you think that Rafa will marry Xisca and have a family soon?

My friend Hannah claims that Novak Djokovic has already hinted he might propose to Jelena soon, because he thinks that it will be rewarding (like how Roger F. married Mirka). Will Rafa marry soon, like before he retires? Because Hannah thinks these 2 will break apart later on, unless he marries her now. But I think that they're both busy with their "jobs" and Rafa wouldn't want to have kids til he's retired!!
