It's that time of year again. John Battelle has his predictions for the search war for 2005. It's a great list.
Personalized news and search isn't mentioned explicitly, but is implied in the long tail (#4) and in redefining what's possible in search (#10).
The further entry of Yahoo and Google into e-commerce (#7) seems to me like a bigger threat to Amazon and eBay than John says. If Google's AdWords intrudes on classified advertising (see "Google, small business, and eBay") and Froogle becomes the place to find and buy anything online (see "Froogle adds product reviews"), eBay and Amazon will be hurt.
