Thanks for all your input.

I looked over the Vista localization methods recently and it appears to be the same as .NET 2 and win forms. The mechanics might be a bit different but at the end of the day you end up with resource dll's that contain the localized content. Is this what other people think.

Does this mean that I don't have to worry too much about locaized text, it is something that can be done near then end of the dev cycle? (I know the code will have to be culture aware though).

I presume when Orcas is released it will have some language setting on the xaml files and automatically generate resx like resource files.
