Companies use ROI targets to plan their investments
Exactly a company uses ROI to plan FUTURE investments although you pulled the 40% number out of thin air. But if you read closely that's exactly what I wrote.
But MGS4 has been done. Finished, finito, sunk cost. So the investment they made into it is completely irrelevant to the question on what platform they will port it etc.
They will make a port if it is legal and profitable. Not because they somehow need to recover development costs. They might not make a MGs5 if MGs4 was not profitable though.
