What's interesting to me is that the source claims they usually get this kind of information 10 days in advance...
Perhaps they are going to have an event on friday the 17th (9 days from now) and are sending out invitations this friday.
Apple has, on occasion, held events/product releases on fridays instead of tuesdays you know.
OR perhaps there will be no event and they will be released this tuesday (6 days)... we shall see.
