For those that read too much into the slogan: "Join us for a preview of the future of iOS and Mac OS X." We've already had a preview of Mac OS X Lion, so what preview of Mac OS X are they talking about now? According to them, it's still considered a "preview" even though we've already had one. So logically, that means we may still have a preview some time in April and another preview or perhaps even an actual release of iOS 5 at WWDC, correct? What are your thoughts?
