Black Hound, a game for PS4 and XB1, is also being announced for a "currently unannounced Nintendo console", making it seem more likely that the reports of third party devs being happy with the NX are true. I believe this is a Hideo Kojima game, not entirely sure.
Whether or not the NX will be digital only (I still find this highly unlikely), it's pretty cool that Nintendo may finally get some third party support again.
