Street Fighter VI likely won't be a thing for another 7 or so years since Capcom's staying the course for long-term support of SFV (which will likely entail for 5 years of DLC counting Season 1 & 2 extra years of SFV Capcom Pro Tour support). By then, we'll probably be on the 2nd wave of NX hardware. It's a shame, since I would have loved to practice SFV during long car rides.
Speaking of Street Fighter, I'd love for Nintendo to start doing Arcade games on the Virtual Console again so we can get Super Turbo & Third Strike.
I know, I was just listing franchises that'd maybe be viable.
I guess I could've said "Final Fantasys, REs, Street Fighters on Nintendo Hardware" to indicate no timeline, if that's more clear
