1. Making search searchier through steady improvements
2. Expand infrastructure and data centers; enhance with speed, depth, flexibility
3. Push more server-based applications to reduce reliance on traditional PCs
4. Expand advertising channels (that's where the money comes from) through video, audio, and print
5. Scare the bejeezus out of Microsoft (and eBay too)
Got to love the last one. :) Also, expect some more cool tools that have no direct relation to search. But do relate to expanding the advertising channels.
