With the impending arrival of Apple’s Worldwide Developers Conference, held annually at San Francisco’s Moscone Center, the rumor mill is certainly churning. Now that Apple is off the roster for next year’s Macworld Expo, this year’s WWDC will have to quench the Mac addict’s thirst for new and improved Apple products. However, that doesn’t mean that the internet remains rumor free. Let’s take a look at the WWDC news circulating the tubes about this summer’s big event.

What we do know for sure is that the iPhone 3.0 operating system update’s summer arrival will mean a flurry of new features for iPhone users, including the long-awaited copy and paste feature and the ability to send and receive photos, contacts, and audio, as well as push notification. And, according to a developer, the new update could make USB tethering a possibility. However, fans are holding on to the notion that Apple will announce a new iPhone to accommodate the software update, one which would include video recording capabilities, a compass, and a 3.2 mega-pixel camera. In addition, an accompanying iPod touch that could mirrors of the features of the iPhone--excluding call capabilities, of course.

There’s also Apple’s next Mac OS X update, which will include some of the biggest changes to the next-gen operating system since Apple first previewed the software at last year’s WWDC. Snow Leopard will come packaged with a completely overhauled user-interface. Additionally, Quicktime will be included in Snow Leopard's redesign to accommodate Snow Leopard’s sleek aesthetics. And though the internet has tried to reach an agreement on an official release date, we can be certain that Apple will announce that at this year’s WWDC.

Among the most abundant of rumors are the Apple netbook and Apple Tablet. Though the latter may seem the most likely, it appears that the company is not considering netbooks at this time. There are also a few unexpected rumors floating around, including Blu-ray support, an updated MacBook and MacBook Pro and the possibility of Apple displaying at a Walmart near you. Steve Jobs will also make an appearance at Moscone Center this year, though there are speculations of his retirement.

Regardless, whether we’re retiring our old iPhones or awaiting the arrival of Snow Leopard, WWDC will be sure to offer Apple fanatics something more to look forward to.

Don't forget, Mac|Life will be blogging live from the WWDC keynote at Moscone Center on June 8.
