This is awesome. The Giants have done one, and so have the Cubs. The Twins will film this during their next home stand. Although they're still working on getting it together (who will appear in it and what will they say), it makes sense for the Twins to do this since Twins Territory (Minneapolis and St. Paul especially) has a large GLBT community.
In somewhat related news, the Twins personally apologized to two women who were scolded by a security guard for kissing.
