Adding to the suspense, Eddy Cue, senior vice president of Internet Software and Services at Apple, boasted earlier this week that Apple’s lineup this year was the best he had seen in 25 years.
What’s the company got up its sleeve?
Although consumers will likely have to wait until later this year for big product announcements, industry experts say that the company may roll out some new features in its software at the conference.
The tech giant is expected to focus on two big themes at the event: health and connecting the home. And the company could introduce features in the new iOS8 that will enable iPhones and iPads to act as remotes for home appliances as well as introduce more health and biometric capabilities in the software.
“For Apple, it’s all about having all the devices connected and getting people even more locked into their ecosystem,” said Carolina Milanesi, chief of research at Kantar WorldPanel.
“It’s trying to add value to devices that we already have. In a sense, Apple is going to everything it can for the iPhone to become indispensable. They want to make the iPhone the center of everything I can do.”
The company’s iBeacon system is one way the company is tackling the home automation market. Using the system enables hardware manufacturers to build in iOS controls so that people can control non-Apple devices via their iPhone.

For example, GE announced on Thursday that it would be integrating iBeacons in its new LED lighting fixtures. This remote for devices would work similar to how Apple’s AirPlay function works, which allows people to control their Apple products by using their iPhone or iPad.
The company’s competitors, including Google, which recently bought the smart thermostat company Nest, are all making plays in the space and time is ticking for Apple to do the same.
“Right now, it’s all a fragmented experience. They are going to start to connect things together,” said Jordan Edelson, CEO and founder of app software developing company Appetizer Mobile. “Apple is going to have to make a push into that realm, they can do a lot this by using the iPhone. They are just trying to connect the dots on all of these things.”
Also related to improving Apple’s home experience, the company may implement Siri capabilities in Apple TV, Edelson said. This would help the company compete with Amazon’s Fire TV, which is voice enabled, he said.
Health and fitness
Apple fans shouldn’t expect an iWatch that tracks their fitness just yet, but they should expect to see the company reveal more about their push into health and demo some ways the new operating system will capture fitness data.
Apple has remained mum on the rumored Healthbook app, which is speculated to be an app that aggregates a person’s health and fitness data tracked by apps and devices. WWDC would also be a good time for the company to reveal more about its initiative considering its competitors are ramping up momentum in the space, Edelson said.
“Samsung has made a big play in this space, but no one has got it right just yet. Apple waits, but they will eventually get it right,” he said. “There’s no reason they shouldn’t be in this space.”
With rumors of the next iPhone and iPad having larger screens, there’s speculation that the updated operating system will enable split-screen capabilities on the iPad.
This would help it compete with the growing number of tablets flooding the enterprise space, Milanesi said.
Apple could also begin to introduce more changes to its mobile interface, Edelson said.
“The next big jump is an augmented reality interface and motion tracking,” he said.
The company could also open up more to developers, including allowing them to develop for Apple TV as well as giving them access to Siri and possibly opening up its fingerprint sensor.
