iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
iWatch Mass Production Might Start in November
We believe developing the hardware and OS of iWatch will be a much more difficult task than for Apple’s existing products.Kuo points out that the iWatch uses many new hardware technologies, like a flexible AMOLED screen, a sapphire crystal cover and a much smaller form factor with higher waterproof standards than other highly advanced Apple devices. Additionally, Kuo notes that redesigning iOS for the iWatch may also be proving a difficult challenge for Apple.
Apple has reportedly been aiming to debut the iWatch at an October event, and has recently hired former Nike FuelBand team members and TAG Heuer's sales director leading up to the expected launch. While there aren't any reports on what the actual device may look like, there have been reports that there could be "multiple versions", which could include watches with up to 10 sensors and a 2.5-inch screen. Apple has also been meeting with athletes to test out the device's fitness capabilities.
With Apple aiming to debut the iWatch in October, it's likely the Cupertino company launches the device well after its debut when production is in full swing, similar to the launch of the Mac Pro. Alternatively, Apple could launch the iWatch in limited quantities and increasing them once production fully ramps up.
