Splatoon will sell over 1.5 million easy in Japan. Final Fantasy will be lucky to sell 1.5 million...
So, the TRULY question is, will FFXV sell more than Splatoon?
No, that's seriusly hard, i can see 10% chance for happen.
Splatoon is too strong.
And of course, i talk about Japan, Globally, the gap will be abissal...
Short versione: Splatoon will sell more than Final Fantasy.
