$10 bil of money means Nintendo has all the money they need on hand to continue to develop for their markets or new markets so what impetus is there to be acquire or merge? Nintendo is not a very big company comparatively.
Ah, merging to get access to money, yes I suppose they don't need that. My uneducated guess is that the reason for a merger would rather be merging the xbox with the switch, and merging the game libraries too. Can't say I know whether that's a good idea.
Yeah that could happen but why? The architectures are different. What benefit is there? Many Japanese companies actually treat North American Market as a secondary thought, Nintendo in a sense is one of them.
