In the US there are far more titles available in Blu-ray, so far, but I don’t have to concern myself with it because I can shop in both camps. I stick either disk into my unit and it plays.

Now that we’re lasing in near-blue, I wouldn’t be surprised if we saw 6 layer disks that hold 300 gig, maybe even more. There is a theoretical limit based on the diameter of the laser beam and the materials available for building disks but we have some room to grow before we reach it.

If either camp dies, it will be bad for consumers. Competition is a good thing. It spawns inovation and narrows profit margins.
