If Nintendo has the following
Japan:
Final Fantasy series
Dragon Quest series
Monster Hunter series
Tekken/Soul Calibur series
Resident Evil series
Yokai Watch series
Kingdom Hearts
+ some more nichey Japanese titles
The West (must haves)
Madden NFL and FIFA
Minecraft
The West (3 or 4 of these franchises is good):
Batman Arkham
Call of Duty
Grand Theft Auto
Red Dead Revolver
Assassin's Creed
Elder Scrolls/Skyrim
Mass Effect
Battlefield
Star Wars: Battlefront
Destiny
Mortal Kombat
NBA 2K
If Nintendo can get even 3-4 titles of above block of franchises regularly to their platform ... that would be OK.
I want all the Japanese support though. If XBox One can have most of those franchises, Switch, which is going to be the market leader in Japan should have them too. The only reason to deny them is if the games are simply unworkable on Switch, and I'm beginning to believe more and more that that is not an issue. Sure some compromises may have to be made but so what, a lot of games are compromised from their PC versions to run on PS4 and then on XBox One.
This is not the PS3/360/Wii or even PS4/XB1/Wii U anymore, the gap is much, much smaller now. I don't want to hear excuses from Japanese devs, not this time. If Switch was the no.1 platform in the US or Europe, you bet your ass it would get every multiplat because every major company's board of directors would insist on support in the West.
