Fatal Frame V [not] confirmed for the rest of the world, but Itagaki believes it will come

It's only sold 60k in Japan, no way that's enough to recoup the production costs of a HD game. 

Wanting to break even or a least minimise losses should be motive enough to release it worldwide. 

Then again, if they don't, it will be hacked like Fatal Frame 4, so it's really just a matter of how long we'll have to wait. Either way, we're getting it.
