While there are things I really like about the system, yeah I don't see a lot of third party stuff doing well.
Dragon Quest (in Japan), Minecraft will sell, but stuff like Skyrim, FIFA, NBA, I think are unfortunately gonna do the same thing Wii U ports did, which is go bomba.
Nintendo's gonna have to support this mainly on their own with 4-5 big Japanese IP and some smaller nichey Japanese games + indie titles.
