Today Microsoft listed 24 new PDC 2008 sessions, but there have been no formal announcement of these that I have seen yet.  This brings the total from 155 to 179.  They are promising over 200 total sessions.  We can expect a few more sessions to be announced at PDC (after they make the big announcements) and perhaps some other updates before then.

You can see the full session list here: https://sessions.microsoftpdc.com/public/sessions.aspx

If you haven’t yet registered for PDC 2008, the registration is still open.  If you have questions, read this post to see why you should attend.

Not surprises around these tags at all, but its nice to see where new focus is going.  Personally, I am disappointed that there wasn’t more added to “Wcf” or “Oslo”, but at least i have the “Cloud Services” to keep me busy. There was an addition of one new tag: “CRR”.  This is Microsoft’s Concurrency and Coordination Runtime. The session with this tag is:

The Concurrency and Coordination Runtime and Decentralized Software Services Toolkit
Get an overview of Microsoft’s CCR and DSS Toolkit 2008 and the technologies it contains for building loosely-coupled, highly concurrent, and distributed applications.

Some of the new interesting topics to me appear to be:
