I seem to recall hearing that v10 would include support for spatial files as a data source. This would avoid all of the conversion steps that are currently required. Was this dropped from v10.0?
Yes, it is still in development.
Looking at 10.1 Beta feature list I don't see it there either :/
This was released in 10.2. However, it still does not support spatial objects in databases. If you want that too, please vote up https://community.tableau.com/ideas/7242
