Well, NINTENDO thinks that getting into bidding wars to moneyhat exclusives is a rarely a good idea. I think there's always room for debate on whether they're right or not. This is the internet after all! ^_^'
That said, I've often wondered about some other developers with traditionally close histories with Nintendo hardware, like Shin'en, or 5th Cell. I'd be curious if Nintendo might start directly "outsourcing" some projects to them, like they often do with small Japanese developers (TOSE? Alpha Dream?) sometimes.
And personally, I've really enjoyed the story about High Voltage Software this generation. It's always invigorating to root for the underdog, so I've had daydreams of Nintendo doing something with that particular independent studio for awhile too.
That said, I wouldn't consider Nintendo as having made huge commitments in western development during this past gen. Partnerships with independent third parties, like Next Level Games and Monster Games, yes, but not commitments. I think their conservative nature factors against rapid expansionism, and that they're worried about employee churn in a second party, something which I guess is much more prevalent in the west versus Nintendo's more traditional, lifelong-job-esque Japanese offices.
