Sony hasn't even begun to release all there accessories for the PS3. I think that you can by a external card reader from like Wal*Mart or someplace an it ill do the same thing. They came out with the PS2 memory card adapter b/c they knew that every one would be needing to transfer there files so they coul keep on playing PS2 games on the PS3.
As for the wi-fi. You can look up Play Link by Logitech. I have two one for my mom's computer and one for my PS2 and sis's computer. They are reeally simple to use and no instalation or special adapters are needed. Since its hard wired for both ends, you can have a wireless conection to your PS3 to the router and not lose a connection unless your internet goes out. Here is a link for the product, I give it *****. They have come down on the prices a lot.

Will Sony make a Wi-Fi add-on for their 20 GB version in the future? Will they also make a memorystick reader? Thanks.
