Considering Nintendo's history with third parties, I'd say it's unlikely. It's possible, but something needs to change big time. But as it is, I'm expected there to be some third-party publisher support initially, then some indivual third party publishers supporting the console later. Indie developers will probably support the console better than big publishers, at least in the long run, as long as Nintendo doesn't become hostile towards them (which is something I'm not expecting to happen).
