Apple sent invites today for an event that will take place on October 23 at the California Theatre in San Jose. As you can see on the invite the company says:
"We've got a little more to show"
We can interpret this "little" as Apple refering to size, rather than quantity, thus refering to the iPad Mini. This rumored version of the iPad is said to have a 7-inch screen.
We will have to wait and see what Apple will show us next week. Once the company goes on stage we will give you all the details of everything they announce.
