100% agree.
Is impressive how people keep saying this and this, but Japan Studio probably wasn't that expensive to maintain, in comparison with studios like ND with as leaked before, have unlimited budge from Sony for no reason.
And we have people joking over that silly Spider-man 2 selling more than Mario, when in reality Mario dev cost was tiny in comparison with Spider-Man 2 so little effort for Nintendo just to get profit, we have fanboys keep focus into sales numbers while with is most important the profit vs costs. Fanboys don't care about the cost of the production.
Even John from DF said similar things in his last DF Weekly, that those western studios are expensive just for keep them alive, mainly California.

"With a studio that size, with many staff members based on California, thats got to be insanely expensive"
