Apple all set to announce iOS 6 tomorrow, but what else?

Apple's annual Worldwide Developers Conference is about to start tomorrow and as usual, it's a big industry event - one, which has seen the announcements of new iPhones, new iPods and iOS versions in recent years.

Eye-witness photos of the Moscone West convention center, where the event is held, show the place is being rigged up for tomorrow's event. And the new banners confirm the highlight of the opening Keynote will be iOS 6, the next iteration of the mobile OS.

It's good to know we'll be getting another major release, but bear in mind the final version won't come out before fall. Perhaps we'll see several beta versions come out before that to give us a taste of what's coming. We have a small roundup of the stuff supposed to go in the new release, but there will surely be a lot more.

What's even more interesting is the things that were left out of the banners. Rumors suggest we might see certain developments in the MacBook series - unveiling of a refresh or even a complete discontinuation of the Pro series, making the Air the single MacBook in the lineup. Another expected debutee would be the final version of Mac OS Mountain Lion.

But whatever it is, you can be sure we'll be here covering it for you as it happens, so stay tuned. The event's keynote starts Monday, 6 p.m. London time.
