The Oslo Perl Mongers are hosting a workshop for quality assurance (QA) from April 5-7 ("most likely", as the wiki says right now). It doesn't necessarily mean "Perl QA", either. They are inviting QA people from any language.
"Nothing has been decided", but this is a true workshop. They are inviting people who want to work on QA things, and taking suggestions for people they should invite. They are also trying to sponsor the travel costs for people. Already committed are some of the people you would expect: Adam Kennedy, Ricardo Signes, Andy Armstrong, Michael Schwern, Adrian Howard, among others. Many others have expressed interest but have not committed.
