ANN:

The box will include about three minutes of new footage as an epilogue that will depict the future of the main characters after the last television episode. However, production of the box will only be green-lit for a March 26 release if 2,000 or more pre-orders are filled.

I already have bought the DVD set. And now they announce this? I'd like to tel P.A.Works up where to stuff their pre-orders. Not that I rage about it or anything.
