Apple formally announced details of its upcoming iOS 6 update and shed some light on a few of the over 200 new features making their way into the new mobile operating system.

Due out in the autumn - likely with iPhone 5 - the update promises several enhancements to Game Center, although few details were disclosed about these new features.

During Tim Cook’s presentation, slides in the background mentioned both Game Center Challenges, Game Center Friends from Facebook, along with Game Groups but these were not specifically touched upon.

The integration of Game Center with Facebook is an interesting proposition, and we expect more information on this to surface as the release of iOS 6 nears.

In with the new

Siri, Apple’s digital assistant, will be coming to the new iPad in iOS 6 and will bring along a host of new supported languages (Spanish, Italian, Korean, Mandarin, and Cantonese).

Additionally, the iOS 6 version of Siri will be able to update a user’s Facebook status, post to Twitter, and launch an app or a game through voice control.

Apple also unveiled their new Maps app that will offer turn-by-turn navigation guides, spoken directions, and photo-realistic 3D rendering with its Flyover feature. Maps will also feature Real-time traffic information and local search results with integrated Yelp reviews, current deals, and storefront photos.

iOS 6 will be available for iPhones (3GS, 4, 4S), iPads (2 and 3) and iPod Touch (4th generation only) although Apple is quick to note that not all features will not be available on all products.
