What will be the best selling game of Gen 8 in Japan? For reference, I've made a spreadsheet of the current 25 best-selling games in Japan, as of the last VGChartz update (these are also numbers from VGChartz, so some of them aren't exactly on point). Will Pokemon X/Y be dethroned, and if so, by what? 

I can't see the spreadsheet . . .

Edit: Now I can. Anyways it'll be a 3DS game. Probably Pokemon.

Same, image is broken...

....and fixed. :)

It will either be pokemon or FFXV

lol every single game on that list is on a nintendo platform! Thats insane

How could FF15 sell over 4.5m units in Japan?  

Are you serius?

No way for FF XV break 4,000,000... and even 2,000,000...

it will be lucky with 1,500,000.

Any way, it's between Pokémon and Yokay Watch... i said Pokémon.
Yokay Watch have good chance for beat Monster Hunter.

Holy smokes, 3DS just fills the sheet with a few Wii U games sprinkled. The only game that I think has a chance is FFXV.

Pokemon XY will probably remain at number 1...

FFXV would sell well, but it is not as popular in Japan than the West.
