Before we plame 3th party we need to know the specs and design of the NX, maybe its just way to expensive for developers to port the games over or the console is too weak or a different architecture, etc etc

Actually even on the GameCube most multiplats sold way better on the PS2 and even XBox. Things like Soul Calibur 2 were the rare case of a GameCube version selling on par or slightly better because they put Link into the game. 

But the GameCube still did get a lot of third party games. 

Wii and Wii U's problem is the hardware simply can't adequetely run the versions of games that developers are making, not without serious sacrifices or having to rebuild the game from scratch. 

It's entirely possible NX is in the same boat. 

This is an absolutely ridiculous notion. Very very few AAA third party games have sold well on Nintendo consoles since the SNES, and that certainly wasn't because the PS1 was easier to develop for than the N64.

There's major major IP theft concerns with this solution.

Gamecube did not get the important tird party games. It got okay japanese support and token western support. It didn't even have GTA. Of course the audience would primarily be on other platforms when Gamecube got treated so poorly.

It didn't have GTA, MGS2/3, and Final Fantasy primarily but that's because Sony had exclusivity deals in those days and that wouldn't happen today because games cost too much to develop for a third party to do that sort of thing with a major release. 

Nintendo still had their share of exclusives/premiere titles ... Resident Evil REMake, Resident Evil 0, Resident Evil 4, Tales of Symphonia, Baten Kaitos, Star Wars: Rogue Squadron II and III, Monkey Ball, MGS: Twin Snakes, Sonic, Final Fantasy: Crystal Chronicles exclusive and Viewtiful Joe first. And most Western third party multiplats like Madden NFL, SSX, Prince of Persia, 007: Everything or Nothing, Time Splitters 2, Soul Calibur 2, Beyond Good & Evil, FIFA, Lord of the Rings, NBA Street, etc. were on the system at least. 

lol, compared to what Nintendo gets these days, the GameCube was a freaking oasis of third party support. 

Also probably because Nintendo is the only console manufacturer who first has to prove that its console is actually selling.

You make it sound like Nintendo got bullied out of third party support by Sony and Microsoft.

Care to explain why third party games sold so poorly on the Wii with a 100 million install base? Developers didn't even care that Nitnendo was so terrible to work with, the install base has everyone clamouring to make Wii games! It's just too bad Wii owners didn't buy them.

I'm glad you mentioned the Wii. Because it proves my point. First to correct your major error. Wii did not get good support. Most of the industry hated it. Just look at gaming news articles from that time. If you don't agree about that then you have the memory of a gold fish.

There are examples on Wii that we can compare to other systems.

The age-old port of Resident Evil 4 sold on the same order of magnitude that the new release of it did on PS2.
Muramasa outsold its predecessor odin sphere by a lot.

Call of Duty 3 OUTSOLD the PS3 version.

It's always the same with you people," third parties sell worse on Nintendo, except for when they don't, let's not count it when they don't"

Nintendo would've gotten a ton more support had the Wii be given competent hardware, they charged $250 for a souped up version of a $99 console (GameCube) with a plastic controller thrown in. 

Nintendo easily could've for $250 made the Wii way more powerful than it was, the XBox 360 had a $299.99 model and that was released a full year before the Wii. 

Blame Nintendo on that, and your COD example doesn't even make sense .... the Wii did get more COD games, so Activision did support it, what exactly are they supposed to do, magically make the XBox 360 version run on hardware that's like 1/10th the spec? 

The PS3 also we know sold like shit its first year being $600 and all, subsequent versions of COD on the PS3 pulled away from the Wii in sales I believe.

Wii's third party situation is entirely on Nintendo, no one put a gun to their head and forced them to make the system an overclocked GameCube. They would have gotten every single multiplat under the sun had the system been able to run those games. If the GameCube at $199.99 was a full generation leap over the N64, there's no excuse for the Wii at $250 (with a plastic controller that cost maybe $15 at best to mass produce) to not have provided a huge upgrade in performance.
