Here is the thing. Blu-ray has sold about 11 million discs since it's release

In it's first two years DVD had sold 16.3 million discs

So right there you can see Blu-ray is quite behind DVD.
Considering that's just hard numbers, and not adjusted for the fact that the movie industry has rapidly grown since then...
When you compare actual disc sales Blu-ray is FAR behind DVD. When you adjust for the growth in the number of movies sold per year.... Blu-ray is well... unbelivably behind where DVD was.
