According to Famitsu, the new Pokémon Red, Blue, Yellow, and Green for the 3DS have sold 69, 234 units in stores over just the short span of two days. As is suggested, such a feat is impressible, considering these number of sales only tallies the number of download cards purchased in a store, rather than including eShop purchases.
Pokémon Red, Blue, Yellow, and Green for the 3DS are rereleases of the original versions on the Game Boy in their respective years, with Pokémon Red and Green releasing in Japan on February 27, 1996, Pokémon Yellow releasing in Japan on September 12, 1998, and Pokémon Blue being sold to the general public in Japan on Octover 10, 1999. Pokémon Red and Green are not to be confused with their respective remakes, Pokémon FireRed and LeafGreen versions, which came out at a later date for the Game Boy Advance.
The 3DS games released via the Nintendo 3DS eShop across all territories on February 27,2016, with a price of $9.99 in the West.
As a proud owner of one of original 1996 Japanese Pokémon Red Game Boy version, I am glad others get to embark on the adventure that started such an iconic franchise.
