It doesn't seem to make sense for Nintendo to release it, not at least until they've saturated the market with snes classics OR have decided to stop putting them out. Starfox 2 was given key placement on the box for the classic, right on top of every other (and in my opinion better) game featured on the front of the box. Once the console fizzles then I'm sure it'll be out in some downloadable format. Switch Online just started putting a few NES games out, i'll bet once the 64 classic comes out the SNES stuff starts hitting on switch online, then i'll betcha Starfox 2 shows up.
Star Fox really didn't age well for me. I just had de ja vu, if I've said this elsewhere please forgive me.
I was excited about playing a new star fox on the snes classic but found myself bored with it quickly.
The more i look at Starlink the more I think Ubeesoft made Star Fox's successor. Zero killed the franchise for me, but it looks like Starlink has resurected the series into something a little more relevant for me.
