Also, barring some type of natural disaster, Nintendo willl never, EVER stop making systems. It is the ONLY thing they do--it's not a division that they can just drop. Yes, Sega was the same way, but they are much more knowledgeable about the industry than Sega was. They are not dumb enough to release a console every year, they know how to make a profit even when they lose a console war, and come on, it's NINTENDO!
Could you imagine a gaming industry that didn't include Mario? Didn't think so.
