I suspect that the Reliance shots weren't actually indicative of any plans for a new home video release at all. They were probably commissioned to do work for the planned 3D theatrical screenings, and then when that project fell through, the work was scrapped before completion. They could well have had it up on their website just to show that it was something they had done, but weren't expecting people to latch on to it as an indicator about a new release. The video was taken down pretty quickly once the online rumors and speculation started, so they didn't want to give people the wrong idea.

This seems all the more likely given that this digital release is apparently just recycling the 2004 master yet again. If they had a new and complete master, you'd really expect them to actually use it, SE or not.
