I still think Animal Crossing is going to be the hydrogen bomb that blows the charts up. Smash, Zelda, Metroid, etc are games traditionally popular with men, but Animal Crossing is massive for both genders and will move some serious hardware because of it, in my opinion, even more than Pokemon. 2020 going to be nuts and we don't even know probably 90% of the games going to be released in it.
I'm of this train of thought too. Animal Crossing is ridiculously popular with near-on everybody.
It also has something that the other heavy-hitters don't on anywhere near the same level - a massive hunger for a new entry, the last was New Leaf way back in 2013, near on 7 years ago.
AC is going to be huge, it's going to sell 20m+ LT imo.
