Of course Capcom will try to correct their ways from this year after their inexplicably weak support for the system, and EA will bring just the bare minimum after FIFA underperformed (compared to everywhere else, at least). The rest are a more interesting gamble. Activision can always try to bring one of the Modern Warfare remakes and just say it's a "Switch version" instead of full remake, plus Overwatch, Hearthstone and other stuff. Ubisoft can bring a decent amount of things, from Far Cry 3-4 to the South Park games to more Rayman (the old 3D ones would be nice) and maybe something else too. T2 will bring GTAV and, if the stars align correctly, a port of Red Dead Redemption.
Also, I'm sure the japanese publishers are delighted to see this thing doing well, just think about the potential sales of PS3 and medium-low PS4 port of JRPGs. We're going to have tons of those.
