I'm leaning in the direction of him having the costume more than not.
I think that the crowd that will get to see the video and will buy the album (or even parts of the album online) will be exponentially higher than the percentage that will actually get to go to see a concert, so either way, its not like it is going to kill his album sales if he debuts some new things at a concert show, whether the album is out or not. One way or another we're going to hear those songs at some point, most likely which will be late June, so Al probably has less reservation about playing them during a show where it is going to be leaking in a massive torrential outpouring of material, as opposed to if he released all the tracks online before the album was out - now THAT might seriously affect sales.
