pokemon usually have good legs and it is newer among the three... not sure how much boost BOTW will get when 2 release..... I think pokemon Sw/Sh will surpass both games in two quarters

Why is pokemon less likely to hit 25 mil? Last nintendo shipment update to dec 31 had SSBU at 17.68M  BOTW at 16.34M and Pokemon SW/SH at 16.06

Pokemon was the last to release and is almost catching up to the others. In the Famitsu numbers it has outsold the other two in january and february so at least in japan is still selling faster and if the ww numbers are similar in ratio it should be above zelda in the next update.

Zelda BoTW has sold 25mil??

Zelda BOTW is at 18.01M

The answer is North America market where Zelda BOTW has charted 32 months out of 34 months since it was released on the market. 

In some European countries Zelda BOTW is already charting above Pokemon SwSh in weekly basis. 

There's no doubt in Japan Pokemon SwSh outsells BOTW greatly but on the ROTW Zelda BOTW is remaining strong while SwSh is already struggling to keep up with the pace. 

Pokemon is also very front load seller. 

That exactly what happened during SMO vs BOTW in 2018. 

SMO had opened at 9M while BOTW switch+WiiU was at 8.2, fast forward SMO is at 16.59M even with official bundled + Mario theme sales promotion while BOTW is at 18.01 without having none of SMO kind of sales deal. 

If 3D Mario failed to keep up with BOTW's legs then Pokemon with much worse reputation in that part will performs much worse. 

Smash Ultimate, on the other hand, is performing insanely well in NA and doing greatly in Japan. 

Well, I can guarantee it will sell at least ONE copy! :D

But I think it's going to sell a TON!

And I mean TONS!

Maybe even an entire ONE MILLION COPIES!

I can't even count that high in under 277 hours.

No,  he thinks all those games will end up above 25m lifetime including Zelda. Only mario Kart 8 has done it so far is above 30 if you include the wii U version 

Zelda seems to be more Popular outside Japan. Where did you get the 18.01 figure from?

Those are official numbers from Nintendo themselves NS version was given in the recent investors report while the last reported sales from Nintendo on the WiiU version was 1.61m

WiiU Version: https://www.resetera.com/threads/legend-of-zelda-breath-of-the-wild-has-sold-over-13-million-units.96763/

Switch Version: https://www.nintendo.co.jp/ir/en/finance/software/index.html

The total brings it to 18m although NS sales were to the end of December so is higher at this point due to the game's continuous sales of at least 1m a quarter since release.

It would take 259,196 Switch cartridges to make a ton.  Selling tons would mean at least 518,392 copies.  Of course, all physical.  Seems pretty likely that it will sell tons.

You can find it in Nintendo financial reports for WiiU number. 

Someone on Era already compiled those stuff for easier view
