Ratatouille on Blu-ray Nov. 6. That should be a good format on which to appreciate the gorgeous animation, but almost every title coming out is only on one HD format or the other, so these "exclusive to Blu-ray" or "exclusive to HD-DVD" announcements don't excite me.
This is an example that the pursuit of individual interests within a group of sellers does not always lead to a global maximum. The studios are killing sales of both formats because the average consumer will not buy two DVD players just to watch their hi-def discs (well, okay, maybe I will, but only because I'm a video quality fiend). With both camps trying to carve out the biggest piece of the pie for themselves, they've shrunk the entire pie.
