What is the current breakdown of active teams in ArenaNet?

[Aidda.8027]

I am still in mourning to learn there is no active guild team at ArenaNet but that got me thinking. What are the current teams and how has the structure of the teams changed over the years. Is the current event team working on just the Joko invasions or are they doing something? what is the longest team? what is the newest team? Thanks

This is something I would like to know, especially in regards to which living world team is responsible for what.

For example, A Bug in the System was developed by the team behind Flashpoint. It would be interesting to have a list of all LW teams, their past episodes's work, and which team is responsible for the next episode.
