Apple has sent out press invitations for their iPad 3 unveiling, set of March 7 at 10am PT. The invitation reads:
We have something you really have to see. And touch.
The image shows a finger lingering over the iPad dock, and as with the iPhone 4S invitation, the icons are cleverly used to provide information: San Francisco on Maps, March 7 on Calendar, and Keynote. (They couldn't include the Clock icon showing the time since iPad doesn't have a built-in Clock app like iPhone does.)
There's no Home button visible, but the simplest explanation for that is the iPad is being held in landscape orientation. Also, the icons are all rendered very crisply, almost Retina-esque...
The iPad 3 event (if that's the device name Apple is going with) will take place at the Yerba Buena Center for the Arts in San Francisco. Along with the widely expected Retina display, the iPad 3 is also rumored to be getting a better, perhaps quad-core processor, and 4G LTE networking.
iMore reported the March 7 event date back on February 13.
