One of the primary advantages Blu-ray has versus HD DVD is the fact that the discs support multiple layers. Sony said they're working on discs with as many as 8 layers, bringing the total capacity to 200GB. Nice.
But before we get there, we need to dual and quadruple layer discs first. Panasonic has announced they've begun initial production of the former, and they'll be shipping out sample units before the end of the year. They already have an English press release [1] available, so go ahead and take a look if you're interested.
