In a way too going to "unifed" approach will be a bit of a relief for Nintendo, now they don't have to worry about the console division constantly or have it be a drain on their bottom line, or having to sell a home console alone to developers, consumers, and support it with an entirely distinct library and try to continually make a sales pitch for it when consumers keep ignoring it.
If people buy the home variant, great, it's like icing on the cake. If they don't, so be it, Nintendo can still all their games to the 60-80 million people that will buy the portable variants.
Right now they have to do all this heavy lifting trying to convince people to buy a console and build its userbase to 20-30 million+ so that they can sell games like Pikmin 3 and Mario 3D World to a decent sized userbase.
Unless they have a miracle gimmick like a Wiimote that catches on at exactly the right time (with no competetion around), they really have had all types of headaches trying to convince people to buy their home console for the last 12-13 years.
I have to imagine in a way Nintendo is looking forward to the Fusion/Unified Nintendo Hardware-Era because it frees them of that stress of having to push a console division, it must be like try to push a giant boulder uphill for them.
