The new Secure Digital Extended Copy is being updated and will now be capable of two terabytes of storage and a transfer speed of 300MB/sec.  At this rate we will probably see memory cards replace Blu-ray discs and optical media in the future, as the transfer speed alone is 100 times faster.  Think of the space savings you would have with such a card.  Your stack of movies and video games will now fit in the same space as one or two of your current games.
