The newest one is this:
G.F.F. Mini Fig. FA Gundam Clear Type for Tamashii Nation 2009. This will be a special gift for the entrance to that event. The entrance ticket is 500 Yen, ad presenting the ticket on the day of the event will entitle you for this Mini Fig figure.
While stock last, so the early birds to the event on the first day - March 26th will get it I believe.
