I think that might be what happens, and I think what could follow is Nintendo becoming more like the LEGO company. 

LEGO has movies, theme parks, theme stores in shopping malls, etc. ... I think Nintendo might be headed down a similar path if amiibo is a big hit. 

Perhaps not a Nintendo-only theme park, but I'm sure Universal or Disney would be happy to work with Nintendo on a Nintendo themed attraction/area. 

It could become a central part of their business pillars with games perhaps moving into a role of being just one of three pillars -- toys/media (movies and theme parks), gaming (Fusion platform), and quality of life (which I think will be aimed primarily towards senior citizens). 

No.

These toys and merchandise goes towards the ultimate goal of selling more hardware and software.

Nintendo was already a toy company. Video games are toys... duh!

Sony has a 400 dollar toy and Microsoft has a 4/500 dollar toy...

All video games are toys, just Nintendo is more of a toy company than others.

How about a fourth pillar?

Although I'm sure they'd have toys and games there as well...

It's something that should've been happening years ago, frankly.

I m sure they just want to expand into other business so that if tits become shitz, they have a backup plan but I think they will still mainly focus into games

Remember they said that they were an entertainment company, and they are also expanding into quality of life products.

well that will be hard in japan, sega is allready there and the market will shrink.

atleast in the traditionel parks segment.  if nintendo can build a park for the elder, that would be like printng money...

Not quite. It's about making more money. If Nintendo can succeed in making money hand over fist making games on its own hardware that also appeal to people (not just kids, but probably that'd be the key mass demographic) who buy merchandise then that is the direction they should go in.

Would people rather they stick to only mario, zelda, smash bros, etc? Because I hate to break it to people, that might no longer cut the mustard. One giant mega hit like pokemon does not overcome an onslaught of other decent sized hit games.
