It's all about market perception. Rumors have as much to do with it as the products they actually release, if not more. People are always trying to stay ahead of the curve when it comes to stuff like that.
Sounds like a bunch of Hooey. Who cares what some Market Analyst thinks? Also we all know the iPhone will be out at the WWDC. Why would he say no, it probably wont? This is idiotic. He is just trying to create an uproar and market variation by getting under the skin of "less informed" investors.
