I'm not sure how to feel about Nintendo's new structure. I generally think that overly-centralized structures, with rigid hierarchies and lots of micromanagement from the upper levels, strangle creativity and hinder diversity. I think that this has been a problem at Nintendo for quite some time now. And, although we don't really know how the new model is supposed to work, at first glance, it seems even more centralized than before.
When Nintendo announced their plans for a restructure, I was kinda hoping for a move toward a more flexible and decentralized structure at the company. Like maybe finally letting their more experienced staff form autonomous studios with their own, unique, creative cultures and the freedom to develop games without being obligated to follow the ideals and usual design principles of the company's old guard.
Basically, I would like to see Nintendo letting creativity flourish the way SEGA did in the Dreamcast days. Or, if that's too risky for Nintendo, maybe move towards a structure with multiple, autonomous, divisions (similar to their old R&D model).
