Here is an excerpt from Apple's official announcement:
CUPERTINO, California—April 14, 2015—Apple® today announced that it will hold its 26th annual Worldwide Developers Conference (WWDC) June 8 through June 12 at San Francisco’s Moscone West, with more sessions than ever before streamed to developers. At WWDC, Apple’s renowned developer community will come together to learn about the future of iOS and OS X®, helping them continue to create the most innovative apps in the world. WWDC will feature more than 100 technical sessions, over 1,000 Apple engineers, hands-on labs to help developers integrate new technologies and fine tune their apps, as well as the Apple Design Awards which showcase the best new apps in the last year... Source: Apple.comApple has announced that this year’s WWDC 2015 is going to be bigger than ever. Something we need to wait to test it out.
Also from the official logo of WWDC 2015, we can see that it looks slightly similar to the Apple TV that is currently available. Maybe Apple might expand its Apple TV into new areas, who knows? Apple sticks to the adage "A picture is worth a thousand words" which refers to the notion that a complex idea can be conveyed with just a single still image. I observed that the big Apple company uses this technique in announcing its new product lines to build curiosity and twist the minds of its product's fan base.
Well I, for one, am very excited to see what new stuff Apple has packed in at WWDC 2015 especially iOS 9. Are you?
