Monster Hunter Frontier G hasn't performed as well as expected.

Capcom has cut its forecast for net profit in half from 6.8 billion yen (roughly $66.1m) to 3.3 billion yen ($28.9m).
They contribute this cut to “rapid changes taking place in the market for games,” stating that their expectations for Monster Hunter Frontier G and “mobile contents” have been lower than expected.
Capcom also increased its annual sales guidance to 101.5 billion yen ($987m) from 97 billion yen ($943m), contributing the rise to sales of Monster Hunter 4.
