On the internet, before an Apple event like the one on September 5th, a rumor round up is mandatory. I'll flog this horse with as few words as possible, mmkay?
• iPods. A fat nano, an iPhone-ish one with touchscreen, RED shuffle. Maybe WiFi.
•iTunes Wireless functionality for either buying or controlling or streaming. No idea what anyone is talking about here. Not much proof.
•Beatles on iTunes, based on the phrase "The Beat Goes On", which has appeared in the Beatles' last press release. Or Not, and instead, ringtones for the iPhone.
