I do remember always hearing that any DVD set, has to be announced roughly 3 months before the release date, to give stores time to promote, advertise, and make space on their shelves. If you said it was a November release, then it could still happen, but it is almost August, and still nothing about any DVD set. I remember the '04 boxset was announced in February, and the '06 boxset was announced in May.
Anyway, I hope you are right, cause if this rumor is true, I think we can finally enjoy the movies again.
