'Longhorn Fever'

Yes, there is a 'Longhorn Fever' - stuff that's not just good but great! This appears to be a quantum leap in Microsoft computing. There have been notable efforts to provide information regarding Longhorn (e.g., the exceptional effort by Robert McLaws) and the forthcoming PDC will be awashed in it. Lucky attendees! Question: What is (or will be) the state of 'unmanaged code (& COM)' under Longhorn? To those of us in the 'Orinoco flow' (developing .NET & COM) this is very much an issue. I guess I'll know more on Oct 31st.
