Europa will be released before Yukon, and it is not likely that many VFP based applications will use or need Yukon for a fair amount of time. The enhancements for datatypes and other features in Europa for SQL Server will carry over to Yukon usage, but there will be some specific features in Yukon that will be best developed using Whidbey. It will be interesting to see in 2005 how many VFP based applications using SQL Server 2000 will upgrade to Yukon. Technical details won't be released until next year, probably at the Advisor VFP DevCon in the fall of 2004 when we launch Europa.
