True, but it's his job to communicate as the head of software the required resources to work on the company projects, that way the CEO can authorize the staffing/facility/budget changes. It seems that Miyamoto failed to properly measure the changes/challenges that having 1 HD console to develop along side the 3DS required. It was his job to express the increased resources needed in order to comply with the forecasted schedule for the software projects.
really? M&A projects are usually not done or triggered by production managers. usually they are either triggered through strategic decisions of the upper management level or in cases were good opportunities arise (bancruptcy of companies in the same field for example). in many cases only the CEO and CFO and a few people are aware of such intention to keep the purchasing price down too. i dont think miyamoto ever was in a position to trigger M&A projects.
