It's that time of year again, the time when Apple computers gathers members of the media to show off it's latest and newest line of products for the coming year.

This year, the event will be held on September 9 in the Fresco Arts Center in Cupertino California, right where Apple is situated. This also marks a return to the location where Apple co-founder Steve Jobs first announced the Macintosh computer 30 years ago.

Shrouded in mystery, one can only guess at what the California-based company will announce. Evidence and history point towards a brand new iPhone, rumors and speculation call for a wearable device, no one will know until the unveiling on Tuesday. We spoke with Canalys' China mobility analyst Wang Jingwen about what Apple might have in store.

Of course, Tuesday is still a ways off; we can speculate all we want. Here are five things that we expect will happen on Sept. 9.

Wearable Device

Wang expects the big reveal on Tuesday will be Apple's first foray into the wearable computing space. She says that while it can't determined what the name and what the final scope of the device will be, Apple is expected to pull out a wearable, be it a fitness band or a watch.

A move by Apple into this space is heavily anticipated. Other brands such as Motorola and Samsung have already announced and released smartwatch companion devices for their phones.

Wang says that Apple's device could be similar to a companion device, one that requires an iPhone to run.

A new iPhone or rather two iphones

Traditionally speaking, Apple has announced a new iPhone in it's September event every year. Last year, they announced the iPhone 5c and iPhone 5s, the year before that, the iPhone 5. This year, Wang says iPhone will announce the iPhone 6.

"We expect there will be two iPhones this year, a 4.7 inch screen model and a 5.5 inch screen model," said Wang.

Leaks of the new "bigger" iPhones have been slowly trickling out all summer. Wang says that despite the unconfirmed nature of the leaks, they have been right in the past and moving to bigger screens is something that can put Apple back into competition with Android smartphone makers.

The upgrades and features of the 4.7 inch phone

As per new upgrades, Wang says the new iPhone, whatever it'll end up being called, will sport new features that make it more power than the previous generation.

Such features are unknown right now but history shows that there will at least be a major software update. Apple is expected to release the eighth version of it's iOS operating system with the launch of the new iPhone.
