"While there may be rumors of an iPhone launch at WWDC, we expect Apple will host a separate event in late June to launch the device. But Apple will not fail to deliver new products at WWDC," he wrote. "Apple has announced that a full-featured version of OSX 10.5 Leopard will be demonstrated and handed out at the event. This means that we will finally see how Apple will integrate Windows operability into Leopard."
Munster added that he "expects" new MacBook Pros to make a showing at the developer conference and that it's "also possible" that Apple will introduce a redesigned iMac.

Similarly, he said, iMacs have traditionally seen updates every 168 days but the current generation is now a whopping 257 days old.
