Apple’s biggest event of 2021 is taking place tomorrow (14th September) and, naturally, there has been a lot of excitement and speculation.

The exact details of the event remain a closely guarded secret, but leaks, rumours and Apple’s past record can all give us a reasonable idea of what might be announced.

You can find out for certain from 6pm (UK time) on Tuesday, but for now, here’s what we think might be unveiled.

iPhone 13

The next iPhone is definitely on its way and Apple has tended to announce the new models of its flagship product in September.

There’s a chance that there will be more events throughout the autumn, but if this is when the iPhone 13 is officially launched, expect it to be the star of the show.

Apple Watch Series 7

We’re also expecting to see an announcement on the next iteration of the Apple Watch, and the rumour mill suggests that it will be quite a substantial upgrade.

Last year saw little more than a couple of new sensors in the same body, but this time there could be a full redesign and improvements to sleep tracking and blood glucose monitoring.

AirPods 3

The third-generation AirPods are also expected to feature, and Apple is likely to move them closer to AirPods Pro, with improvements including shorter stems and a longer battery life.

Other outside bets could include the new iPad Mini and new MacBook Pros.

It’s likely that any big iPad and MacBook announcements will get their own events, assuming that this one will be dominated by the new iPhone.
