Is Microsoft going to support SQL Server 2008 with LINQ in Visual Studio 2010?

Is Microsoft going to support the features of SQL Server 2008 such as Hierarchyid and Filestream with LINQ in Visual Studio 2010 at last?

Thanks

P.S: Tired of having features in SQL Server that Microsoft's own tools don't support. Please let me know if it's worth the upgrade.

While there haven't been any official announcements, MS has made it pretty clear that Entity Framework is the future, and that significant enhancements won't be made in LINQ to SQL (here's a list of what's new in L2S for 4.0). L2S isn't going anywhere, but I wouldn't expect to see any of these features get lit up anytime soon, either.
