Can Nintendo ever produce a relevant home console again?

[Soundwave]

Well what if the portable NX sells 60 million units and the console version sells 15 million ... the unified platform thing kinda throws "what's successful" into a bit of a blender.

Which is probably part of the appeal to Nintendo. Now if the console sells like garbage, it doesn't really matter that much because they can still sell the same games to the wider audience that still buys Nintendo handhelds (though that group is shrinking).
