Apple already has a set-top box, but has been mum on when it might produce its own TV. That hasn't stopped technology publications from weighing in, and the rumors have gotten louder recently.

The says "a trusted source" confirmed that Apple is planning to demonstrate a new version of the Apple TV operating system at its Worldwide Developers Conference June 11-15 in San Francisco. Supposedly, the new OS is more feature-complete than the current version and is the same one that will run on Apple's much-rumored upcoming HDTV.

"Our source believes Apple won't actually show its physical TV at WWDC, but it's certainly possible," reports BGR, which, just a couple days earlier had written that "Apple's Chinese manufacturing partner Foxconn has to build an Apple TV set." It cited Chinese news website Sina.

In addition, Piper Jaffray analyst Gene Munster has written a report that shows him standing firm to that the Apple television is coming.

His reasons, according to , include: supply chain information, things Apple CEO Tim Cook said recently at The Wall Street Journal's D: All Things Digital conference, information included in a biography of Steve Jobs written by Walter Isaacson, as well as other third-party reports.
