If you look at the numbers of first party games released it's about equal to those released the past 20 years on Nintendo consoles so it's about the same. Nintendo was a little stressed supporting 3DS AND a HD console. Oh and look around at every developer these days is vastly over challenged by HD development. All these AAA devs are over worked and over staffed and still we have insane delays and releases of broken games still released early despite delays. Indies like Hello Games or Comcept are clearly over challenged. Nintendo now willonly have to worry about Switch so that will help.
Point is yes Nintendo is to a degree but should be eased soon but most developers still are over challenged by HD development..hell so many of them have closed last 10 years.
