I hope it's nice. If they hit a home run with this and it's actually a good alternative to enjoy these games on a modern HDTV, it would be a shame to be all but limited to wired controllers.
They could've just directly copied the d-pad on the NES. That's what I'd of preferred and those patents are all expired.
I disagree
It very well might not be financially practical to pursue, but I don't think it's from a lack of gamer interest. Among those willing to spend over $100 on a device to improve their 8/16 bit Sega/Nintendo gaming experience in 2013, I think you'd find a healthy percentage of those individuals with some interest in the NEC platform from that time.
Plus, aren't they also selling these in Japan where that system was a much larger success? Much like how I bet the North American market wasn't the driving force behind them making revisions to accommodate Master System gaming (I would imagine Europe is more to thank for that), that's something that it has in its favor.
