Here is something else that might help Warner sell on both formats and still give the upperhand to HD-DVD (in addition to the True HD tracks.)
, Warner has not yet released any 'Super-special-fully-decked-out-kitchen-sink-included-multi-disc' edition of the HP series similar to what they have already done with 'The Matrix' trilogy.
Here's the thought:
Warner whips up a super special set of the Potter series. They go all out... including new transfers, all sorts of bonus materials, extra scenes, features, the works, etc.
They then release them to DVD, HD-DVD, and BlueRay. No problem there as both HD camps get the release. The catch is that the HD-DVD and DVD versions are one and the same. Combo discs, with a price no higher than it would be if it were DVD only.
I think Warner could get away with doing 1 combined DVD/HD-DVD SKU in that case, as they could probably press enough combos to keep up with the smaller demand for such a box set.
I wonder if they weren't mulling the idea of something similar with the recent 'Superman' box, because that would have been another seemingly perfect application for this strategy.
It seems to me that it would be a good strategy for getting HD-DVD into more DVD collections while also satisfying the Blu people.
