Apple may break from tradition and delay the announcement of its next-generation iPhone 12 until October, due to coronavirus and travel restriction delays.
The firm is holding a virtual event from Apple Park in Cupertino, California from 18:00 BST on Tuesday where new devices and services are expected to be revealed.
Rumours suggest that Apple will unveil the new iPad Air and Watch Series 6 at the event, as well as details of the new Apple One subscription service.
This is the time of year Apple usually confirms new iPhones - it was September 12 last year - but the firm said new iPhones won't be available until next month, fuelling speculation that it could hold a separate standalone event in October.
Production delays in China, travel restrictions worldwide and related issues linked to measures designed to slow the spread of coronavirus are behind the delay.
Rumours have suggested that Apple is set to release four new iPhone 12 models, including a 'Mini' iPhone with a 5.4-inch screen, but not until October.

Apple has announced a major launch event for next Tuesday where the firm could unveil the iPhone 12. The tech giant’s website shared a new post in its upcoming event section that reads, ‘Join us from Apple Park. September 15, 2020, at 10am PDT'
With details of the new iPhone models likely delayed until next month, Apple is expected to spend Tuesday's event focusing on a range of other products.
New aspects of iOS 14 and the latest release of watchOS and iPadOS are expected to be unveiled - including new augmented reality technology.
The invitation to the event, featured on the Apple website, is an 'augmented reality Easter Egg' - floating in front of you when visiting the site on an iPhone.
One of the major new developments rumoured to be included in the next generation iPad Air is a TouchID sensor incorporated into the On/Off button.
This would allow Apple to remove the home button and create an 'all-display' design similar to the iPad Pro or iPhone 11 - without the added cost of FaceID.
The next generation tablet is also expected to take other features from the iPad Pro including replacing the lightning port with a USB-C connection.
This would allow for charging with USB-C cables used in most high profile Android devices, the MacBook Pro and the iPad Pro.
There may also be a new iPad Magic Keyboard released alongside the new tablet.
Apple Watch Series 6
The latest version of the Apple Watch - Series 6 - is expected to feature the same exterior design as the previous generation smartwatch released in 2019.
However, rumours suggest the new wearable device is likely to include battery and power performance improvements due to a new 'system-on-a-chip'.
There are also likely to be improvements to the water resistance of the watch, faster WiFi and mobile data and a new blood oxygen monitoring system.
This would add to the health and fitness features on the device - alerting users if their blood oxygen levels drop below a healthy threshold to get help quickly if they are suffering from a respiratory or cardiac problem.
There are also rumours the wearable device could get some mental health capabilities such as showing breathing exercises if it detects a panic attack.
Apple may also launch a new cheaper Watch option to replace the Series 3 - possibly a modified version of the Series 4 but without the ECG app and 'always-on display'.
Continuing its push into the services sector, Apple is rumoured to be launching a new 'all-in-one' subscription service called Apple One.
It will provide a lower cost bundle of the various Apple subscription services such as Apple Arcade, Apple TV+, Apple Music, Apple News and iCloud storage plans.
It would allow customers to subscribe to a combination of these packages for a single price, rather than requiring users to have multiple subscriptions.
The firm is also rumoured to be working on a Peloton style fitness subscription service linked to the Apple Watch and delivered over
