Glad to see SNK getting in on some deals. And glad to see NIS finding an audience on other platforms, that seem to have users that are losing a degree of interest in them.
Really, if developing for Switch audience means we'll get different games than we'd get if NISA of SNK were locked to PS4, then... fine. Same with SNK and Treasure last Gen. Some games just wouldn't be made under certain sales projections and audiences. Heard it from working designs, heard it from Treasure, seen it through lots of stuff that gets greenlit on Vita but not PS4, Xbox 360 but not PS3, or Saturn and not PlayStation.
I also really have to wonder if the Anniversary collection would be any way near the same, if not for being on Nintendo's platform. The Home Versions (And Crystallis) are going to be NES versions most likely, right? While there have been NES games released on other platforms (Rare Replay and Capcom's Disney Collection come to mind), it still seems to take more work.
As far as Heroines, Wii U had Tekken Tag 2 ports with Mario costumes. Pokken Tournament is basically a Nintendo exclusive Tekken skin. A Retro Street Fighter Port was nearly a Switch first-string release. As much as Nintendo is trying to have an esports push, I think it's smart of them to get a pool of games to interest the audiences that are suppose to be playing ARMS and SMASH. And Heroines is basically a walking promo for Hamster's old SNK releases, which are a big supporter of the thirsty Virtual Console-style market that's bringing oldschool shooters and new games like "Dragon Marked For Death" from Inti Creates onto the system.
Heck, a years exclusive from Nintendo got us a New Bomberman game. Which is now releasing on basically everything, and has been getting great support for it since release. There's way less sting to such deals than there used to be, even compared to 2 or 3 years ago.
