On Tuesday, Apple has started sending invitations to the press for a special event scheduled on September 5, MacScoop has learned from journalistic sources.

The event will take place at the Moscone West exhibition centre in San Francisco and will begin at 10 a.m. (local time).

The invitation shows a silhouetted figure as those we've previously seen on iPod ads and reads the slogan "The beat goes on", which refers to the end of the Beatles' last press release.

Apple is clearly expected to renew its iPod line-up during this event. Rumours of next generation iPods and iPod nanos have been spreading on the Internet very quickly during the last few weeks.
