The fact that the 2012 invitation says that attendees need to "see" this year's update has been viewed by many as a reference to the high-resolution Retina Display that is expected to be one of the defining features of the next iPad. There has been reports leading up to this year's event that the so-called "iPad 3" will feature a 2,048-by-1,536-pixel display, doubling the resolution and quadrupling the number of pixels of previous iPad screens.
The invitation ALSO said "Touch," which the Apple Insider story cleverly avoided remarking on because they have no idea what that part of the invite might be about.
I predict that Apple will also introduce a new iPod Touch, perhaps with a 7" display.
Remember folks, you read it hear first!
