A source with Boy Genius Report said that Apple will soon be putting huge cloud capabilities in iTunes. This could almost eliminate the need for you to store content from iTunes on to your device (what normally takes up a big chunk of your iPod Touch or iPhone hard drive). These new capabilities will allow iTunes to:
1.) Stream music and movies from Apple to your computers and devices.
2.) Stream music and movies from your computers at home to your other computers or mobile devices.
3.) Wireless sync iTunes with devices.
