I think the truthful reason why individuals like myself wouldn't be impressed and people like Kresnick would be disappointed, (I am fine with 400k) is because Persona 4 and Persona 4: Golden together has built a larger audience and that we hope for the growth of this franchise. Remember Persona 4 and Persona 4 Golden build the audience up, and now we hope it continues, namely when PS4 is supposed to be the new market leader.
To add, it is good if the franchises grow, and that is the hope of us fans or enthusiasts. Also if something enters some what stagnation or decline, it could be troublesome sign as well for a franchise that is as healthy Persona.
