From my point of view, and not only that, iTunes is a complex, poorly thought out program that works extremely hard on Windows. Apple has had a lot of complaints about iTunes over the years and it seems that 2011 will be the year when the company is thinking about restoring the program without which we cannot use an iDevice at the moment. In September should see version 11 of iTunes, a version completely redone by Apple that will bring new design elements, will bring many new functions and of course will bring compatibility with the iCloud system. Basically, iTunes will be able to synchronize backups from iCloud and will have a new interface for the App Store, but at the moment we only have rumors available.
From what we're hearing, the UI would be much cleaner and "slick." iCloud is also going to be more closely integrated with iTunes. Rather than the iTunes Store being essentially a web browser, the Store will actually be integrated into the entire app—much like Spotify is currently.
We're also hearing that iCloud backups will be integrated into iTunes. This means if you back up your iDevice to iCloud, that same backup will be stored locally on your computer. Also, app data from iCloud will be synced closely with iTunes. For example, if you beat a level in Angry Birds, that level data will be synced to iCloud and then to your iTunes library.
For now, it is not known when exactly this new version of iTunes will be released, and considering that Apple is trying to gradually abandon this method of saving data and reinstalling the operating system, it is possible that we have a little more to wait until we see iTunes 11. I'd be happy to see a program that works as it should, doesn't have an aberrant information synchronization system, and offers decent support for the most widely used computer platform. Until the release of this new version, we will have to get used to iCloud, an equally imperfect system that is currently available in beta version.
At the moment the "biggest" version of iTunes is 10.5 beta which is only available for application developers who need to install iOS 5.
