Apple on Tuesday sent out invitations to a special event on October 22 in San Francisco, revealing little about what is expected to be a day devoted to iPad updates.
Emailed invitations bore few details other that time and place, and bore the message "We have a lot more to cover."
A colorful graphic the shape of an iPad showed the top of Apple's iconic logo under a shower of colorful leaves.
The invitations came about a week after unconfirmed reports that Apple will show off a new version of its popular iPad tablet computer that will be thinner than its predecessor and boast improved camera capabilities.
An upgraded version of the iPad mini with an improved screen is also expected.
The iPad remains the largest-selling tablet, according to surveys, but its market share is being eroded by rivals using the Google Android operating system.
Apple was also expected to discuss its computer operating system and its laptop line at the event, timed for the start of the year-end holiday shopping season.
Apple is coming off a wildly successful launch of two new iPhone models last month. The California firm said it sold a record nine million iPhones in the three days after launching two new versions of the smartphone.
