Although INP stopped subbing OP awhile ago, it looks like they picked it up again just for this movie. It isn't announced on their site (http://www.instantz.net/) yet, but you can get the torrent from here:

There are 2 versions - xvid/avi and x264/mkv - both are 848x480. I haven't watched it yet, so I can't comment on the quality.
EDIT:
1080p, 720p, and 480p versions from a Blu-Ray rip have now been released as well. These obviously don't have "Sample" in the video the entire time like the previous releases.
