Look, for us to say we're going to go through a whole generation without an HD capacity drive I think that would be naive to assume that we'll be sitting here at the end of the Xbox 360 generation and nosuchdevice will have shipped.
This being a prototype, the Samsung rep we spoke with had no clue on what such a device might cost or when it might come to market -- or even if this thing will ever see the light of day, so don't get your dual-hopes up just yet.
