So you have a 3-layer, 45GB HD-DVD? That’s nice kid, here’s a nickel. 4-layer, 100GB BD is where it’s at.
If they can get this standardized soon, it is possible that 4-layer support will be included when units start shipping, like in the PS3. Maybe with a software upgrade. Just like many DVD-R drives are designed to handle DVD-R-DL with a PROM flash.
Admittedly, 100GB discs are far more likely to be used for data than video. Even with minimal compression 100GB would hold a hell of a lot of video.
