NX will receive all games edited by Nintendo, smartphone games, handheld games and home console games... I'm not sure Nintendo need Other editors...
In fact, power is not what's going to decide third partys.. It's selling of NX 

I'm writing this not knowing the actual performance of Tegra x1 in this regard but on surface examination it looks like 4 64bit arm cores and 4 32bit arm cores. Typical for a high end android phone. Like the wii u this looks like another cpu light design that is far less competitive in cpu performance in comparison with its gpu performance so again its not competitive with current ps4 or xbone let alone the newer models coming.

Surely we should remove all references to home consoles and just see this as a portable system with a hdmi connector to a tv. Even wii u has larger optical discs and more storage potential with a usb 2.0 hard drive connected.

Any ps4 or xbone ports it gets will be severely cut down and a non event to most gamers who want the best versions of games.

The NX will get;

Nintendo's own brilliant titles
Portable games from the publishers who supported 3DS
Enhanced versions of android or other arm based games
A few horrible versions of PS4, PC or Xbone titles that people will reject commercially for obvious reasons before the publisher concerned wise's up

mass effect 1 wasnt pn ps3 either as ms2 released.

All this octa cores are just marketing. Neither the amount of cores nor the number in GHZ is really important for performance.

The Nvidia Tegra x1 is alot more similar to apples a9x chip, using a high amount of transisters, manufactured in 20nm (14 would be alot better though).

The Apple AX Chips are known of the best performance chips out there with very similar design as intels i´s cpus. The octacore snapdragon and exynos chips arnt really competitive

Because, as I mentioned in the exact same post you just quoted...

" it required a bit more effort to make full use of the system's capabilities, which was an extra bit of effort that devs weren't willing to go to if few people were going to buy their game to begin with."

The Wii has games that look much, MUCH better than COD. Metroid Prime 3 arguably looks better than any COD game on last gen, and Super Mario Galaxy, while not a realistic art style, was extremely visually impressive as well. The problem was that developers had to go additional lengths to get a good looking game out of the Wii, which was effort they were simply not willing to go to on a system where their game probably wouldn't sell that well to begin with.

The problem with that is, the Mass Effect Trilogy was set to release on PS3/360 in the not so distant future once 3 was released on Wii U. Mass Effect was originally published by Microsoft Studios before EA took over the publishing rights so it might've took some time before the original didn't have to be under the publishing rights of Microsoft.

You failed me Nintation. You failed me.
Nintendo is not desperate for 3rd party support. They are desperate to create an ecosystem they can control totally, regardless of the 3rd party support.

if you think Metroid prime 3 looked better than any of the CODs then IMHO you dont know what you're talking about but that is your opinion. Good day.
