FFXIV Collectors edition.

We all know that we'll be buying the collectos edition becuase it comes out 8 days early, but also you are going to get some cool stuff!
The in-game item as you may already know is the Onion Helm which you can see here:

Also you'll get and authenticator so you can do really secure log-ins and a drink container.

There is other stuff like the map, the book and DVD but I think these are the coolest bits!
