What is the recommended way to build MSI packages in VS 2010?

Last year I heard that Installer Projects were going away and we should be switching to Windows Installer XML. Whatever happened with that?

So you know where I'm coming from, support for TFS-based buil machines is very important to me. I know Installer Projects kinda-sorta work with TFS, but they have issues.

IronRuby uses Wix, but that requires upkeep and scripts. I haven't looked into parrafin or anything like that yet, but the mix of a Parrafin (like) script and WIX would probably work well.
