Predictions:
- 11" Macbook Air (well that's pretty much a given, as is an SSD)
I'd love it to have touchscreen athough that's probably unlikely.- 3G in macbooks
- Facetime replacing iChat, so Macs can video conference with iPhone4s
- more cloud based services - iDisk to be more like dropbox (which is great)
