Software sales are so incredibly low right now on both sides it's quite comical.
Clearly sales have a long way to go for HD media.
However, at this moment in "HD disc" lifecycle (both formats combined sales), HD media is producing higher sales than DVD produced at this same phase in it's own life-cycle.
In other words, side-by-side with DVD's growth curve, HD media is actually doing better.
That's a good sign of things to come for the future, given the tremendous sales increases we saw with DVD as time went by (even if HDM never reaches the same sales level, it has a lot further to go).
