Scalpers are going to be soooo happy if this is true.Seems strange Nintendo would stop 'production', but maybe they were not happy it was 'hacked' and now can play many hundreds of ROMs and different systems also like Sega and SNES and Gameboy, or Nintendo needs production space for the upcoming Switch, or maybe they are going to release NES Classic 2 for Holiday 2017, and it was never in the plans to keep making the current Mini model.
Nintendo has reported they sold-thru 1.5 Million units, and had increased production to supply demand, but now there is rumors they are stopping all production in April and retailers will be getting only a few more shipments and then its no more NES Classic Mini.
Of course this is all just a rumor, and seems to all point to only one source from a Norway (Nordic) Euro Retailer, so maybe its only related to that region alone and there will still be NES Classic Editions available in other countries, one can only hope that is the case!
