What will the controllers/memory cards be like?
They will look the same, but be very different. The Dual Shock 2 will look at feel like the Dual Shock 1, but in the 2 all of the buttons are fully analog. Which will probably be cool. The memory card looks, feels, and is the same size as the PSX memory card. But the PS2 memory card will hold an astonishing 8MB of memory. As for other peripherals, I am not sure.
