Sure, this sounds great, just like Blu ray did. But I think that the only way that this technology would be utilized would be through movies. The size of the current Blu ray disc, when dual layered, is 50gb, and how many games have taken advantage of that? Only a hand full.
Maybe with the next generation of consoles, Microsoft and Nintendo will use physical media with a larger storage capacity, but if they don't, then don't look to this as being an opportunity for large games, or very many large games.
