Dr.Vita said:
Final Fantasy XV will be the biggest game for PS4 in Japan and will easily beat Splatoon.
Final Fantasy will sell 1.5M+.
Splatoon will sell 1.2M maximum.

How the hell you can say 1.2 million is the maximum!? 1.2 million is at least the minimum.

And if you say 1.2 million is the MAXIMUM, you probabily predict less. What is your prediction? 1 million in the intere life cicle? Splatoon will sell nearly 1 million only this year.
