Today, Apple sent out an invitation to members of the media, alerting them of a media event to be held on September 9. While the invites declined to provide any information on what products will be unveiled next week at t event, speculation is that Apple will reveal a refreshed line of iPods.

Apple has held media events in September regularly in recent years to show off new and refreshed iPod models for the holiday shopping season. In 2007 they launched the iPod Touch, and the iPod Nano in 2005. This year it is expected that they will launch updated Nanos and Touches with digital cameras. The Touch may also have a video camera say analysts.

Apple could also use the event to launch the much-rumored, but never confirmed tablet device. However, analysts do not anticipate the launch of this device until later this year or early next year.

There is also speculation swirling around whether or not CEO Steve Jobs will show up. He was on leave for six months, returning to work in June. Apple has declined to say whether or not he will be at the event.

The event next Wednesday will be held in San Francisco at the Yerba Buena Center for the Arts Theater.
