Mingchi Kuo, an analyst at Taiwan-based KGI Securities, issued a report that predicted the delay of the release of the new iPhone and iPad.

Kuo is known for the analysis of Apple Inc's supply chain. Also, some other Taiwan-based industry analysts obtained similar information. The following is a summary of "Apple Watch," which Kuo released April 11, 2013.

We predicts that the new iPhone and iPad mini will be shipped in volume later than the consensus in the market expects. And the growth rate of their shipment volumes in the third quarter of 2013 will be less than 10%, contrary to the consensus (30-40% growth). Therefore, the business performances of suppliers including parts manufacturers may deteriorate.

The specific release schedules expected by the market and us are as follows. The iPhone 5S and iPhone 5 will support TDD (time division duplex).

- iPhone 5S: July (market consensus) and September or later (our forecast)
- Low-priced iPhone 5: July (market consensus) and September or later (our forecast)
- iPad mini 2: August (market consensus) and September or later (our forecast)

The reason why Apple changed the release schedule of the iPhone 5S is that it became necessary to find a coating material capable of being applied to a glass surface without affecting the operation of a sensor used for fingerprint recognition. Also, the company might be taking time to develop software for fingerprint recognition for iOS 7.

As for the low-priced iPhone 5 and iPad mini 2, the plastic case and the Retina Display, respectively, delayed their release dates.
