An Oprah interview would be good, I don't think there will be another interview until the album comes out though. The 60 minutes one was good but it seemed so quick and dumbed down, I'd prefer more of a sit down one. I remember him talking about his mum and not having seen her in 3 or 4 years but he's a lot more forgiving of her now after his addiction (he said he loved her) and I thought that was pretty interesting.
The Hailie thing will never happen, he's done a good job of "hiding" her from the world without going to Michael Jackson proportions and he's not about to throw that away so he can get more publicity for a new album.
