Rumours have been swirling around the web for weeks that three new devices will be released during the famous September keynote with a bigger smartphone and a cheaper all-screen call maker being unveiled alongside an upgraded iPhone X. Apple has considered calling the phone the "iPhone Xr", one of the people said.
While the iPhones will be the Wednesday's main attraction, Apple's growing smartwatch business will see stage time, too.
If the sizes there are accurate - and they probably are given that they seemingly came from Apple's own site - then the Apple Watch 4 could be larger than the Apple Watch 3, which comes in 38mm and 42mm sizes. The Xs Max is nearly exactly the same size as the iPhone 8 Plus, despite the fact that its display is a full inch larger. The phones have a new redesigned Apple 12 Bionic CPU and GPU, exclusive to iPhone XS and XS Max.
Tonight's event is being held at the Steve Jobs Theatre within Apple Park and will start at 6pm United Kingdom time.
The iPhone X also got rid of the home button to make room for more screen and introduced facial-recognition technology to unlock the device. Others have been nicknaming it the iPhone XC - after the iPhone 5c, Apple's last lower-priced experiment.
Plenty of companies would like to have Apple's problem - it has been so successful that it's hard for the company to grow. The most expensive version, the 6.5-inch iPhone, could cost as much as $1,200, and may include a rear camera with three lenses.
In 2017, Apple started selling the iPhone X in November, around two months after its launch. It's expected that the price tag could be as high as $1,200. And on Wednesday morning, another blogger found a confirmation for the phone's model numbers in the sitemap of Apple's website. Apple's offerings may also impact Huawei's P20 Pro.
Apple, which prides itself on being more secretive than the Central Intelligence Agency, has struggled to keep the lid on product news lately.
