Nintendo probably planned a limited run of the NES mini from the beginning. Time to start selling the SNES mini now.
I saw a NES mini at walmart once, but decided not to buy it. I'm not that big of a collector and my Wii and Wii U can run the NES emulator if I ever get the urge to play NES games. If I ever did buy one then it would probably stay in the box to keep the value up on it.
