The Apple rumor mill is about to heat up dramatically because the iPhone-maker has just announced its World Wide Developer's Conference (WWDC) will be held June 2-6 in San Francisco.

The WWDC is an annual event hosted by Apple to show off its new batch of devices and operating systems to developers, offering them an exclusive up-close first look. With the fanfare Apple always manages to drum up, the WWDC has become the time of year people can expect to learn about the latest iPhone, iOS and other gadgets.

Held around the same time last year, rumors of a summer release for the iPhone 6 (if that is what it will be called) seem to be getting flimsier by the day. Apple tends to release its new devices as early as Sept.

"We have the most amazing developer community in the world and have a great week planned for them," Philip Schiller, Apple's senior vice president of Worldwide Marketing, said in a press release. "Every year the WWDC audience becomes more diverse, with developers from almost every discipline you can imagine and coming from every corner of the globe. We look forward to sharing with them our latest advances in iOS and OS X so they can create the next generation of great apps."

Here is the rumor roundup for Apple's latest and greatest.

The iPhone 6 is expected to come in two offerings, like the iPhone 5S and 5C. Only this time the two smartphones could very well be offered in different sizes, as well as each having its own capabilities. Graphic designer Sam Beckett echoed many whispers when he told the Washington Post he expects the new top-end iPhone to have a 4.7-inch display with a 1920x1080 display.

9to5Mac reported iOS 8 will feature a standalone iTunes Radio app and new stock apps, like Healthbook. The website also speculated Apple could be revealing Macbook Air laptops with their ultra-precise Retina Display screen resolution.

It is less clear what some of the secondary devices revealed at the WWDC will be. The iWatch is rumored to not be ready for a 2014 release, but 9to5Mac learned Apple is looking for physiologists to help with its production. This is a clear indication the iWatch will be meant to synch with the Healthbook app, meaning the smartwatch's release may not be as far off as we think.
