Aside from upgrading rear camera module to 12MP, Apple will upgrade front camera module to 5MP […] The new iPhone may not be equipped with sapphire cover lens, as it still has quality issues on the drop test.
Although sapphire is much more scratch-resistant than Gorilla Glass, it is more brittle, and thus at greater risk of shattering when dropped.
KGI also reiterated its concerns over the limited appeal of the new features and external factors that could result in flat or negative growth.
If Force Touch fails to create attractive selling points, together with slowing consumption in China and mobile operators cutting subsidies for high-end smartphones, we expect shipments of new iPhone in 2015F to be flattish from or slightly lower than the combined 73mn units sold of iPhone 6 and iPhone 6 Plus last year.
The other specs predicted for the iPhone 6s are similar to what we've already heard. ie 16/64/128GB storage tiers, 12MP rear camera, Force Touch, rose gold color, etc.
Apple is expected to unveil the new iPhone 6s on September 9th. Please follow iClarified on Twitter, Facebook, Google+, or RSS for updates.
