Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
iPad 3 Front Glass Reveals No Significant Changes: Round Home Button, Camera and Sensor Holes
The part appears nearly identical to that of the iPad 2, with the major distinguishing feature being a relatively long ribbon cable extending up the side of the display as opposed to a shorter cable with a sideways orientation seen in the iPad 2. Other features of the iPad 3 display include the same round home button seen in all iOS devices so far and a hole in the top bezel to accommodate both the front-facing camera and the ambient light sensor.
A separate posting from the same blogger claims that the A5X system-on-a-chip seen in a leaked photo has a dual-core processor and that the iPad 3 will support Siri. The report also claims that the iPad 3 will launch with iOS 5.1 and a rear camera capable of recording 1080p video. Finally, the posting says that the iPad 3 will launch in the U.S. in mid-March with France, Germany, Japan, and the UK to follow in April. Other markets including China and Hong Kong should see the device launch by June 1. The reliability of that report is, however, unknown.
With the revelation of the front glass assembly and earlier leaks of the rear casing, ultra high-resolution display, logic board, and several other internal components, most of the iPad 3's major parts with the exception of the battery and camera modules have now been seen. Apple is expected to introduce the iPad 3 with a media event scheduled for March 7.
