Today's the day. Now that we've all shaken off the rust of a three-day weekend, Apple is ready for its annual iPhone reveal. Expect the event also to include a new version of Apple Watch, a release date for iOS 10, and other announcements detailed below.

The show starts at 1 PM Eastern/10 AM Pacific. Apple will live-stream the event here. Remember, if you try it in Google Chrome it won't work. You'll need to open it in Apple's Safari browser, or watch the show on your Apple TV. (Windows 10 users can view it in Microsoft Edge.)

1. iPhone 7 will finally arrive

Although the event will be about a lot more than just a new handset, the iPhone 7 is still set to be the star of the show. According to the mass of leaks that have proceeded the handset's arrival, however, it might not be the update you've been waiting for.

Hopes of a radical redesign have seemingly been knocked on the head, with the iPhone 7 instead set to sport a 4.7-inch form markedly similar to last year's iPhone 6S. Instead of new materials and curves, it looks likely that those unsightly antenna lines will be reduced and a new dark blue colour scheme added. These minor design differences will reportedly be wrapped around an improved, Full HD display and enhanced camera that has new low-light specialities.

2. Apple Watch 2

Yes, the new iPhone might be the highlight, but it's not going to be the only headline product taking a bow at Apple's September 7 event. The Apple Watch 2 is also expected to make an appearance and, like the iPhone 7, it's expected to play host to a number of key updates, but not necessarily the ones you were hoping for.

While the original Apple Watch stormed to the top of the smartwatch sales charts without ever really igniting the whole market, it's been suggested that instead of the coveted week-long battery life, it will add a FaceTime-friendly integrated camera. Elsewhere, more intuitive app control will reportedly make the cut alongside a marginally slimmer body. There's still no word on a round model though.

3. WatchOS 3

Just because a new, second-gen Apple Watch is on the way doesn't mean your original device, which you only bought a couple of months ago, is going to become a useless paperweight. Instead, a sizeable watchOS 3.0 update is inbound to give it a new lease of life and help minimize the gap to its second-generation counterpart.

While we already know that watchOS 3.0 will add everything from a new multitasking dock and iPhone-esque control centre to enhanced fitness skills and the ability to save your life – really – Apple bigwig Tim Cook won't confirm the software's rollout date until the September 7 event.

4. The iOS 10 release date will be announced

It's not just Apple Watch owners that will be getting a major software refresh. All iPhone and iPad owners will enjoy a software-based update too thanks to the impending iOS 10 release. While we already know about the mass of new features the iOS 10 update will introduce – we're talking everything from enhanced Siri skills to new Messenger abilities – what's still unclear is exactly when the OS patch will drop.

That's all about to change. The iOS 10 release date will be one of the biggest September 7 announcements for cash-strapped iDevice owners. We'd suggest adding September 14 to your diary, with the software patch typically dropping a couple of days ahead of the new iPhone's in-store release.

5. New-look Apple Music

In just a year, Apple Music has gone from "Ah great, another streaming service," to a legitimate Spotify rival. It's all about to change though in a bid to further win over those looking to switch up their streaming options and once again be able to enjoy a bit of Taylor Swift without splashing out on a full album.

A full Apple Music redesign was teased at Apple's WWDC conference back in June, and now it's time to see exactly what the iPad Pro maker has up its sleeve for the coming update. What we do know is that the new Apple Music will be lighter, brighter and more sparsely designed than the existing app. It will also be a karaoke fan's dream with lyrics being added for all songs.

6. iPhone 7 Plus, but no iPhone 7 Pro?

Fans of oversized phones rejoice, you won't be missing out next week, with the sub-sized iPhone 7 set to drop alongside the now customary big boy of the iPhone family, the iPhone 7 Plus. The 5.5-inch take on the flagship phone might not add much that its little brother doesn't have, but for those that favor pocket-stretching screen space, it will be the smartphone of choice for the coming year.

All those reports of an iPhone 7 Pro being in the works, however, look set to amount to nothing. Tipped to be sized similarly to the Plus, albeit with a far superior set of specs and an even more wallet-crippling price tag, the Samsung Galaxy Note 7-rivaling Pro has by all accounts been put on the back burning. Anyone up for waiting for the iPhone 8 then?

7. Mac OS Sierra release date

It's only taken a couple of years, but Siri, everyone's favorite digital PA, is finally set to wave goodbye to its smartphone-centric roots and hit Macs in the coming weeks. When, exactly, is currently unclear, but you can expect that to change on Wednesday.

Unlike the iOS 10 and watchOS 3.0 releases, don't expect the macOS Sierra rollout to be just a couple of days away. Although a beta version of the software is already available for download, the full release isn't expected to drop unlike October, likely alongside a series of new Mac devices.
