Apple invited journalists to an event in San Francisco on Sept. 7 where the company is expected to roll out a series of product upgrades. The invitation showed out-of-focus multicolored lights against a black background. The company is expected to introduce next-generation versions of the iPhone and Apple Watch at the event. The successors to the iPhone 6S and 6S Plus will include advanced photography capabilities and upgraded hardware with a design similar to last year’s models. according to reports.

The spots of light on the invitation form the top portion of the Apple logo, with the message "See you on the 7th" below. The event will take place at San Francisco’s Bill Graham Civic Auditorium at 10 a.m. Pacific Time.

The invitation may refer to a larger version of the new iPhone that is expected to have a dual-lens camera system to improve photography.

The upgraded handset will also include a re-engineered home button that responds to pressure with a vibrating sensation rather than a true physical click and the removal of the headphone jack. The new Watch will likely integrate GPS-based location tracking.

The Cupertino, California company sold more than 214 million iPhones over the last 12 months. But sales are down from a year ago, and analysts will be watching closely to see what changes Apple has made in the newest models.
