The Famicom Classic Edition is doing quite well in Japan so far. In just four days, the little console containing 30 games has managed to sell 262, 961 units.
For those unaware, there are two editions released just a few days ago: the NES and the Famicom. While both systems contain 30 games, both have eight games exclusive to their regions. All the games are based on titles released in the mid to upper-80s, and in the early-90s.
