Apple Inc. (NASDAQ:AAPL)’s 24th Worldwide Developers Conference will start next week, which is one of the most awaited events for tech lovers. The event is also special because it’s the first event from Apple Inc. (NASDAQ:AAPL) after more than seven months.

The conference will run for the full week, but the most awaited part will be the Monday’s keynote address, where Apple Inc. (NASDAQ:AAPL) is expected to announce new products and services. So, before everything is actually revealed on Monday, let’s try and guess on what could be expected in the upcoming event.

Apple iOS 7

iOS 7 is expected to replace iOS 6, which was launched at the same event last year. There have been talks that the overall design will be completely changed. The rumor becomes more a reality after CEO Tim Cook confirmed last week that Apple Inc. (NASDAQ:AAPL)’s top designer Jony Ive is responsible for the overhaul.

Some of the other new features that can be expected are a new interface. A report from 9to5Mac in April claimed that Apple Inc. (NASDAQ:AAPL) may keep the functionality of iOS apps and features intact but exclude few of the overlapping digital features of real world objects in favor of simpler designs. Apple could also come up with more ways to interact with a device through gestures. A report from 9to5Mac expects Apple may add its AirDrop file-sharing service. They might also include more of Yahoo’s content and services to Apple’s devices.

OS X 10.9 Launch At Apple WWDC

Apple will also launch its OS X 10.9 at WWDC. A report from 9to5Mac believes that in the new version, Apple will solve the age old problem that left users with many windows open on their desktop. Apple Inc. (NASDAQ:AAPL) is also expected to come up with a full-fledged version of Siri in the latest version. Also, they might integrate its homegrown maps in the latest version. Apple could also come up with a fix for the full screen maps that didn’t work properly for people with multiple monitors. New multitasking features that improve battery life and processing power may also be announced.

Apple MacBook Pro And MacBook Air

Both the MacBook Pro and MacBook Air are expected to get some new features. Apple may add a pixel-dense Retina Display to the MacBook Air and may slim the MacBook Pro (the non-Retina version) and enhance the quality of its built-in FaceTime camera to support 1080p. It may also introduce the Mac Pro, its desktop tower.

Accessories

Apple Inc. (NASDAQ:AAPL) may also update its AirPort Extreme, Time Capsule and Airport Express. It’s been a long time since the company updated these. A report from 9to5Mac also suggests the same. Apple could also announce the launch of a new version of its Thunderbolt display.

Services

Like Apple Inc. (NASDAQ:AAPL) introduced iTunes Match at 2011’s WWDC keynote, this time it may announce its Pandora-like Internet radio service or iRadio. Also, Apple Inc. (NASDAQ:AAPL) could announce updates to its iCloud services that replaced MobileMe service.

Despite all these expected updates, users will certainly miss the announcements for either a new iPhone or iPad at WWDC this year. Apple Inc. (NASDAQ:AAPL) has used a WWDC to launch a new iPhone in the past, but this time it looks highly unlikely.
