The thing is he's at the point in his career where things will come his way like movie role offers and requests to produce music for other artists, as well as being the spokesperson for Audi and Calloway golf, etc.  He's probably taking advantage of it with the thought that it won't last forever.

I also think it's normal that people would come into this fan site and complain about the lack of a new album.  Justin has far, far more fans of his music than his movies.  Look at the sales!  If people can't complain here where can they complain?

Personally, I give Justin a lot of credit for taking chances and trying to continue to grow artistically in every way.
