If you have worked or had a look on ESB Guidance v1.0, you will truly appreciate the new enhancements that are in ESBG v2.0, from enhancements in the installation process, to having a visual Itinerary designer :) , and even support for more resolvers, and much much more ..

Even if you didn't see ESB v1.0 before, i believe now is the time to start having a look on the exciting capabilities offered by the guidance on top of Biztalk Server. 

You can watch here the video from the SOA Conference about the new ESB 2.0 http://soaconference2009.spaces.live.com/blog/cns!FA6FC7F5DB1C07!136.entry
