Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
5th Generation iPad to Begin Production in July-August
A July-August ramp up of production runs counter to many of the earlier rumors that had suggested the iPad launch as early as April.
While Apple's traditional timeframe for iPad launches has been in the first few months of the year, last year saw two iPad launches -- one in March, and one in November. The late 2012 release of the 4th Generation iPad may have altered that usual timetable.
The new iPad is believed to be "thinner and lighter" than the currently shipping full-sized iPad. The 5th Generation iPad is also believed to take on the same thin-bezel design as the iPad mini. The above mockup is based on leaked iPad 5 enclosures from early this year.
