Apple will host an event in San Francisco on Tuesday, where it is widely expected the company will announce a new lineup of iPad tablets.

The company will likely reveal two iPad models: the standard version with a thinner, lighter design, faster processing chips and a better camera; and a new iPad Mini that will boast a sharper Retina display.

Apple’s event arrives as the company continues to face pressure from rivals launching lower-cost tablets running on Google’s Android mobile operating system. According to IDC, twice as many Android tablets were shipped during the second quarter of this year than Apple devices.

Apple is also expected to unveil a new Macbook laptop computer as well as details on the OS X Mavericks operating system for Macs.

USA TODAY will have live updates from the event from reporter Marco della Cava starting at 1 p.m. ET. Follow this post for the latest from the event.
