As part of the Nintendo Earnings Briefing, the Super NES Classic Edition was confirmed to have sold 5.28 million units, which is twice more than the NES Classic Edition was able to achieve (due to shortages). As a reminder, the Super NES Classic Edition can be seen at stores regularly, and Nintendo has previously announced that the NES Classic Edition (NES Mini) would go back on sale this coming summer.
