The system is two weeks old, the first rumours started in what 2014? http://wccftech.com/rumor-nintendo-working-nextgen-console-soc-selected/ is a January 2104 article on the matter, so late 2013 maybe. 2012 if you want to go really obscure and washy https://mynintendonews.com/2012/06/...king-on-3ds-successor-and-not-a-3ds-revision/ We could consider the development period and when things might have happened but I am not sure what good that would do, it is certainly not like they would have told everybody new home console using fancy intel+direct X 12 a like graphics gear and switched to the Nvidia ARM stuff late last year. Modern development tends not to be all done to a piece of given hardware either and there is some scope to recompile and optimise if the ground shifts a little bit under you, as well as use higher level languages that are less troubled by all this (how many android devs have all different phones to test on as much as saying meh it is all java anyway). People also like to tell me Nintendo has massive reserves of cash. I will take that as read for this. Nintendo have also screwed up for the last however many years (the wii did not do so well for the last years of its life and that was some time ago), and even the 3ds was hardly a shining beacon of light. Game dev studio costs http://www.polygon.com/2014/7/31/5949433/the-cost-of-a-game-studio Get a bunch of those that is already set up and I am sure you could have a bunch delighted to work with and be funded by the mighty Nintendo. Compared to even a rudimentary advertising campaign... To that end there was plenty of scope for Nintendo to have a decent launch lineup and launch window. Instead we have this.
