Retro gaming on the Wii - enhanced!

So, on Retrozone, you can buy adapters to plug in your old Nintendo controllers to your Wii. This is for use with the service Nintendo provides to allow you to play on your Wii nearly every Nintendo game that ever came out for any system. I’m extremely surprised that Nintendo didn’t see this coming! They are going to lose out on potential business! They should have released Wii versions of the old control. Sure, they had a “normal” control in addition to the Wii stick, that looks like a cross between a Gamecube and a Super Nintendo controller, but it’s not the same as playing your old games with the old controllers! I predict that the prices of old Nintendo controllers being sold on Ebay will rise.
