According to the numbers, the new 4k format is growing just as fast, if not faster, than blu-ray was at this point in its lifespan.
That would seem to refute the argument that “not as many people will care about a 4k SE,” but I still think that argument holds water if only because there was already a diminished enthusiasm for these movies when they first hit blu-ray.
The 2011 release made less money in its first week than the 2004 set made in its very first day.
