Nintendo shouldn't release a new console earlier than PS5.

I get where you're coming from but I don't think you've thought about it thoroughly enough.

Did being released over a year early hurt the PS1, PS2 or Xbox 360? History has shown arriving early is normally a good thing. Also Dreamcast comparisons are flawed because Sega simply run out of money. If they hadn't the system probably would have outsold the gamecube and Xbox.

Finance wise, Nintendo has started making money off the Wii U. No one is saying release the successor now and I personally think 2016 is too early aswell. 2017 however would be perfect. They can't ride the Wii U into oblivion because they'll come out the otherside with a very bleak future in the console space with their only hope of success coming through software sales. Where has the underdog ever made significant ground by releasing after the popular choice?

Tech wise, Nintendo doesn't need to wait for the others to release their specs to be within the ball park they simply need to communicate with 3rd parties and manage those expectation against what they can afford. Because of diminishing returns, I don't see it being hugely important whether Nintendo match the PS5 specs, they just need to easily trump PS4 and X1 by a fair margin.
