i honestly don't see a world where nintendo tops the next generation. maybe in terms of consoles + handhelds, but if you're judging it that way, they came out on top during the n64/psx gen too.
their nearly two-decade problems with third parties persist, and the wii u is this weird thing that nintendo doesn't seem to know how to present. more than that, its online structure will lag behind its competition quite noticeably.
