I don't think he is going to retire, but it wouldn't totally suprise me. He doesn't need fighting. He has openly said he plans on returning to the Croatian special police and possibly public office. Having Big Nog in UFC has to be a little disheartening as well. He has 4 fights left on his UFC contract and I don't know if he can get a title shot with three wins. After gonzaga and couture you have to figure that Vera(if his contract dispute is settled) should be next in line. Arlovski with another win and preferably a more entertaining one will be right in the mix. Mirko's best shot is to get a easy win over someone like Mir then beat Sylvia. If he did that it would probably put him right back at the top.
