I hate Sony as a company. But I do enjoy a lot of their games

I'm not sure why every one of their representatives has to speak their mouth about their certain vendetta against Nintendo every chance they get, but it's very bad mannered.

EB games never lists the price right.  It originally said the 3DS would cost $350.

I hope this is true.

I just think it would be really hilarious for some reason.

That's not really true.

Metroid Other M for example wasn't developed inside Nintendo. That doesn't mean it's not a Nintendo IP.

Nintendo can co-develop/publish IPs with devs outside their company.

Yes, but Metroid is Nintendo's franchise.  

Publishing a game does not make it your IP.

It's not at all uncommon for developers to handle more than one title at once, you have to remember that guys like Miyamoto come up with the ideas and oversee the projects, they don't actually have to do much of the labor in programming, visual design, etc...Miyamoto usually has the role as the "Producer" or "Director" in most games and in reality many of the games (even IPs he created) aren't actually created by him (as far as story and such). His job is to give people a clear picture of what to do, then make sure they are doing it. Because of that he (like many video game Directors or Producers) will work on multiple titles at a time checking progress on each periodically.

The thing I've always found odd about Miyamoto is that he's been creating games for over 30 years and yet he himself isn't actually a gamer, and he's regularly stated he rarely plays video games.

So? You don't have to play games very much to know how to develop them. It's kind of like with sports commentators. None of them play the sport, but they have a lot of knowledge about it.
