I know it's early, but does anyone know who is supplying the 768 GB SSD BTO option in the new Retina MacBook Pro? I'd love to find an SSD that large, but cannot find any (at least at anything approaching a reasonable price). Does anyone know of an existing SSD that size for sale at any of the usual places? I realize that the pricing on the new MBP is jacked up, but the BTO option price for the 768 GB SSD isn't that bad for Apple. Any info is much appreciated.
