Looks like tri. Part 4 won't be leaving theaters quite yet...
It will continue on for a 7th week at the Shinjuku Wald 9.
The Wald 9 has acted as a defacto 'home theater' for tri. since tri. began, but I don't believe any of the other tri. releases have lasted this long at it.
tri. part 4 will continue at the Wald 9 thru April 14th, with a decision to come later on if it will continue past that.
No theater gifts has been announced.
