Naa. I think it was a pretty obvious move. Although my prediction was that they would tackle film and music before software. They obviously tried but after seeing what a pain in the ass it is to work with hollywood / music industry gave up for now. They renamed "My Games" into "Library" with Games, Media, & Tools subtabs and after giving up on the whole media bit just have "Library" now.
Software is a more logical step considering they're already set up to deliver software (games).
