According to a source at Digitimes, the iPad 4 will experience a significant delay in its release compared to previous generations. While the new iPad arrived in March 2012, next year's model might not be ready until June 2013 , far exceeding Apple's usual gap between device generations. This publication has also provided some other interesting details ; we'll give you the specifics.

The reasons for this delay could be varied and may be related to the fact that the development of the iPad Mini has partially slowed down the development cycle of the iPad 4. Although Apple's compact tablet will presumably feature many of the components used in the second-generation iPad, the device's design, its new components, and all the operations that must be carried out before manufacturing begins could delay the iPad 4's launch until June 2013.
However, before the launch of this device, the updated models of the new iPad may arrive around March . This has been rumored for some time, and Digitimes' source places its arrival during the "first quarter of 2013." The major innovation of this model would be the incorporation of the A6 processor , which debuted this year in the iPhone 5. This processor was designed entirely by Apple and will likely be the last one Samsung manufactures for the Cupertino company.
Another interesting detail offered by Digitimes is that the development of the iPad 4 is focused on reducing the number of LED chips to optimize power management and consumption. The plan is to replace single chip packages with dual packages, thus improving screen backlighting without requiring the 84 emitters used in the new iPad. The screen size, meanwhile, will remain the same at 9,7 inches, which would rule out rumors of a new 16:9 aspect ratio.
These leaks appear to be coming from supply chain managers in Taiwan . However, other major outlets like Cult of Mac are treating all this information with considerable caution.
