Its way too early to tell to be honest.
Final Fantasy VII remake and Final Fantasy XV are the most obvious choices, Dragon Quest XI if it comes to PS4, GTAVI actually has a good chance.
I'm not so sure about KH3 or RE7, its been so long since a proper KH game on consoles that its likely the fanbase moved on and its not like KH 1 & 2 got to a million easily.
That's pretty much it, no fighting game has a chance the audience is not that large anymore, Tekken 7 and Street Fighter V might not even sell 500k, there won't be a lot of marketing in Japan, they know the audience for those games is in the west.
With the PS3 version MGSV has no change, MSG2 & 3 needed years and plenty of rereleases to get to 1m and that's when the franchise was a monster.
Don't get your hopes up for something like Horizon and COD, Shenmue has no chance either Japan was never too interested in the series to begin with.
