It's really too early to tell.
Inazuma is a known quantity... on handhelds. We have no idea how that success will translate to the console space, but I'd assume it'd do fairly well.
Strictly talking sales, Ninokuni could be anywhere from a mediocre disappointment to an amazing success. Ghibli's involved, which means a hell of a lot, but it doesn't necessarily guarantee anything. Just look at how Gundam performs in the video game space these days.
