2.3 Million in 4 months is going to be hard to top. Especially based on yesterday I believe the demand is even higher due to last years craze,.
It seemed more difficult for me to get a SNES pre-order than it was for me to get a Neon Nintendo Switch pre-order.
I never knew people could get this crazy over 20 - 30 year old games. I still play my SNES, NES, Atari, etc, but I didn't realize so many people cared. It makes me wonder if Nintendo is going to do a NES/SNES compilation cart for the Switch, a N64 classic or a NES Classic 2 for next year.
At this point they'd be crazy not to make this an annual thing.
