Two weeks ago wrote an article wondering if Nintendo would reprint Mario All-stars for Wii. Looks like they read VGPC's blog because they are considering a reprint now.
Wired has an article saying that Nintendo is considering a reprint on Super Mario All-Stars for Wii.
According to Nintendo public relations director Marc Franklin:
"We are gratified by the consumer response to this limited-edition product, which we created to celebrate the 25th anniversary of the original Super Mario Bros. game on NES,” “Because of the strong response, we are exploring the option of bringing this item back at a later date."
Looks like the price will probably be coming down as soon as the reprints hit. I wouldn't be buying the game on eBay right now.
