Apple is as always mysterious about their products and also events, but not this time. They have officially announce iCloud as their main attention on the next their annual Worldwide Developer Conference (WDC) that will be held June 6-10 in San Francisco Moscone West. The tickets has been sold out (as usual).
What's more interesting is that the current CEO, Steve Jobs will be the keynote speaker himself even though he's on leave for medical treatment. WDC will also focus on the new version of OS X 10.7 Lion, and the upcoming iOS 5. It should be interesting as usual. I'm waiting for Job's speech
