Apple's yearly Worldwide Developers Conference has been announced for June 6-10 in San Francisco. Reading their announcement, they invite potential attendees to "a preview of the future of iOS and Mac OS X" but make no mention of any new hardware. We know they will be showcasing software but will they be unveiling the iPhone 5? There is no lack of speculation in that department but with the iPhone 4 still relatively new and the iPad 2 just out, maybe they will be waiting until fall for new hardware announcements.
The 5-day event costs $1600... $320/day for those still counting with their fingers! Add airfare from wherever you might be, hotels and restaurants, and it's going to cost at least a few grand to attend. But wow, what a show it would be - AGAIN!
I don't think Apple has ever disappointed attendees at a WWDC.
