Emily Rogers (yeah, that Emily Rogers) has a wonderfully well-written piece that I think many folks around here should read.
Now, we know about the rumors and speculation about EA trying to talk Nintendo into using Origin for their online services and how everything went to **** between the two when Nintendo said "No.". And this article does discuss that.
But, more important, is that this article goes into details that those of us who have been around awhile already knew, but many people either don't know or seem to forget.
Nintendo and EA have NEVER been BFFs.
This goes back to ol' school NES/SNES days (you know, the days where so many folks seem to think Nintendo needs to go back to with regards to third party relations).
Nintendo, virtually single-handed, revived the video game market that was destroyed in the wake of Atari (with a little help from Mattel, Coleco and what little third parties were around at the time, like Activision).
One of the ways they did this was by brow-beating third parties into submission by what we now would call insane third party agreements. Basically, in order to release games for a Nintendo console, you had to give your first born to Yamauchi and pledge an undying oath to Nintendo. That second one isn't bad though.
Anyway, EA knew these policies where pretty bull**** from the beginning - and thus, they've always had issues with Nintendo.
http://www.notenoughshaders.com/2013/03/25/the-sexual-history-between-nintendo-and-electronic-arts/Go, read the article. It's pretty well researched and contains lots of quotes and links.
Then, remember, a lot of the big companies today (Activision, Capcom, Square, etc.) were around back then... and dealt with the same issues. There's a reason that these old guards of the gaming industry are reluctant to jump into the sack with Nintendo at the drop of a hat - and I don't blame them.
However, it'd be awesome if they realized that New Nintendo isn't exactly like Old Nintendo (and is getting better, although slowly) and realized that, in the business world, running a successful company working with someone you don't like is better than closing an unsuccessful company from working with someone you do.
