I’m a little late out of the start blocks here. The 6th of november the public announcements came from Microsoft for a couple of new products, namely the Serach Server 2008 family.
The big news her imho is the Express version wich (as the rest of the Express products) is free. This will get a lot of people to try out search without making a very big investment. Meaning you still have to have a server to run it on an the time to set it up.
