Today, I was at a MSDN TechTalk about BizTalk Server 2004.
It was a good overview of the product. But, in 4 hours of show, it is not possible to go deeply in BizTalk.

So, I could see a internal build of BizTalk and see that some bug I have are fixed and also see some interesting features. Normally, the final release would have more DB functoids than the Beta.

Normally, Microsoft should release BizTalk 2004 on mid-January.
