According to the countdown timer at the PDC2008 site, the opening keynote is only 17 days away (at the time of writing). The previous PDC in 2005 was all about Office 2007 (including SharePoint) and Vista, but this time there didn't seem to be a lot of Office/SharePoint content scheduled. Not that this is a bad thing; after 3 years of SharePoint teaching, coding and evangelizing, getting to know new technologies can be great. :-) I'm really looking forward to learn more about Live, Live Mesh, Cloud Services etc.
But if you check the PDC sessions now, you can find five SharePoint related sessions. For a nice summary check Paul's blog post here. Hey there will even be a SharePoint booth! So I hope to meet you in LA!
