With Apple appearing to have a full slate of announcements lined up for its Worldwide Developers Conference (WWDC) keynote on Monday, we're offering this roundup to summarize a number of the high-profile rumors that have been circulating ahead of the event. Arnold has done an excellent job of compiling together all of the rumors that have been floating around over the last several months. He does a good job laying out the more or less credible ones too. I for one am hoping for new Mac Pros, and an iOS 6 Beta… Happy Keynote Day everyone.
