According to Boy Genius Report, iTunes 9.0 will have the following features:

1. Blu-ray support
2. Application Management – You will be able to visually manage your apps and rearrange them
3. Social Networking - Integration with Twitter, Facebook, and Last.fm

These are some great features but as of now, they are still just rumors. I do find, however, that the social networking feature is not needed all that much considering iTunes is still just a media player, much like WMP (Windows Media Player) or VLC media player. I do think that the integration of Blu-ray support is a very nice add-on. Because the are still not officially confirmed, we still do not know if this is true. Though if it is, I am curious if it would work on all computers or only on computers that have Blu-ray disc readers. The reason I point this out is because I doubt that if a certain computer does not have the hardware to read Blu-ray discs, what would make software on this computer capable of doing so?

There is no confirmed release date but it is believed to be released sometime near September when the new iPod Touch third generation will be announced (possibly).
