There's two versions of the Issue 9 DLC available this time. The basic version costs 1200 points and contains the mission part of the Issue 9. In addition to this there's a Collector's Edition that costs 3000 points. If you have already bought the basic version, you can upgrade to the collector's version with an extra 1800 points.
In addition to containing the Issue 9 missions, the Collector's Edition comes with an Orochi made barrier trinket, a Sensei title, and demon masks and school uniforms for both genders.
As of writing this, the end of the Whispering Tide is taking place, and the migration of Flappy birds has started towards Tokyo. After the migration is over in 20 short minutes, Tokyo will be unlocked.
Other non-Tokyo related changes include the long waited functionality to see the date your cabal mates have been online the previous time. Read the full update notes here, and Funcom's official Tokyo announcement post here.
UPDATE: You need to be a subscriber to be able to access Tokyo for the next 3 days. If you subscribe now, according to the official announcement, you should get enough points to buy the Issue 9 right away. If you do it now, be aware there might be a bit of wait as everyone is trying to simultaneously buy the required Funcom points to be able to buy the Issue.
