Too many groups thinking things are going to be updated. People who want a new Mac Pro, MacBook Air, Mac Mini or iMac ALL think their respective products will be updated at WWDC. Sorry, not going to happen.
Here's the most likely situation: 2/3rds of the keynote will reveal the new iPhone and further discuss iPhone OS 4.0. The last 1/3 of the keynote might reveal ONE updated Mac product. Definitely not four updated products.
Worst case scenario is that there not even a mention of any Mac products. If Steve does this, I would be VERY surprised.
As for which Mac product will be updated, no one knows, but I believe the Mac Pro is slightly more likely.
