With the 2006 Worldwide Developers Conference (WWDC) quickly approaching, the Mac rumor scene has been buzzing with rumors and reports. As usual, MacRumors provides this Rumor Roundup as a summary of major rumors circulating around the Mac Web before the big event. In last year's WWDC roundup, we summarized the possibility of an Intel-based Mac. Readers should remember that it was only a year ago that Apple first announced they would be switching to the Intel platform. Mac OS X 10.5 (Leopard) Apple has already announced that Mac OS X 10.5 (Leopard) will be discussed and demonstrated at WWDC 2006. In fact, a recent slip-up on Apple's developers pages indicates that Apple will be distributing a Developer's Preview of Leopard at WWDC. Detailed information about Leopard, however, has been very limited. Very few reliable sources of information have come forward. The earliest rumors pointed to Virtualization software to be built into Leopard, but this was flatly denied by Phil Schiller. Job postings, Patent applications and Page 2 rumors point to a focus on updating Finder with extensive and improved integration with Spotlight. This has even been the topic of some presumed fake screenshots. Perhaps the most corroborated claims are ones of Apple's iChat 4.0. Appleinsider claimed that iChat 4.0 will incorporate the ability to call traditional phone lines much like existing Voice over IP services, with similar reports elsewhere on the web. While MacOSXRumors have offered a list of other possible features: virtual desktops, collaborative features, tabbed iChat, the reliability of this source is not entirely certain. Mac Pro The Intel-update to the PowerMac line remains highly anticipated. The first hints at a name-change came in January 2006 when Apple was revealed to have trademarked the term "Mac Pro". This was largely dismissed until Steve Jobs revealed the plan to change the name of the existing PowerBook and iBook lines to "MacBook" and "MacBook Pro". Meanwhile, we received early confirmation in May that the Mac Pro was indeed targeted for release at WWDC 2006. In July, Appleinsider felt confident that Apple had chosen the Woodcrest (dual-core Xeon) process for use in the upcoming Mac Pros. While similar to the recently released Core 2 Duo (Conroe) chips in architecture, the Woodcrest processors allow for multi-processor configurations which have been a feature of the high end PowerMacs. Meanwhile, ThinkSecret believes that the Mac Pro will instead use the Core 2 Duo (Conroe) chips that were recently released. One Page 2 rumor claimed Apple would incorporate both Conroe and Woodcrest into different Mac Pro models, but the validity of this information has been cast in serious doubt. Other features also rumored include substantially different enclosures, dual optical drives and an Intel-designed motherboard. iPhone Despite ongoing unsubstantiated claims that the iPhone will be released soon, there has been very little credible evidence that the iPhone will be seen at WWDC. iPod iPod rumors are more difficult to pin down, as iPod rumors have been circulating in full force for months. Rumors of a full video iPod started in early 2006, but peaked in late March due to Apple's impending 30th anniversary. Subsequent rumors of video iPod delays and difficult Hollywood negotiations have pushed off the release further, with one analyst believing September-October to be a more likely timeframe. In July, however, ThinkSecret had mentioned the possibility of iPod nano updates at WWDC. Coverage Steve Jobs will present the Keynote address starting at 10am Pacific Time on Monday August 7th.
