If those are the only things that the NX has going for it, then I don't think 3rd parties will jump onboard. We already have a semi-clone of the PS4 on the market and it isn't doing nearly as well as the PS4. If Nintendo comes in and tries to go for the exact same market as Sony and Microsoft without bringing a unique concept forward that really sets them apart then I think we will once again be in the Gamecube days where Nintendo has a powerful but poor-selling console that most serious gamers see as "too kiddy."

Fortunately, Nintendo is going for a "new concept" but we just don't know what that is. Cloud-based processing? Handheld/Console Hybrid? LCD with on-screen buttons? There are lots of rumors but I do believe that whatever this new concept is will give Nintendo a unique angle in the market that nobody else has right now.

Nintendo doesn't necessarily need to break the world with a Wii-like success, but they do need the NX to sell more than 30 million units. When 30 million starts to seem attainable, 3rd parties will begin to find it economical to port games to the NX. Third parties are quite simple: they will be there if Nintendo can create the market for them to be profitable but they are not going to create the initial success for the NX.

Western 3rd parties will take a 'wait-and-see' approach with some lazy, low-effort, low-key ports to test the difficulty in developing for the platform. If the NX is a platform with a handheld/console model and a unified library then Japanese 3rd parties (especially Square-Enix, Level-5 and Capcom) will jump on board with full support from the get-go.

No, Nintendo is for man-children that play Mario. Real gamers play Minecraft and buggy Ubisoft titles.

More powerful than the ps4.... but $300 and in only 11 months ? Are you out of your mind? This is Nintendo you are talking about. The apple of gaming... the company that rides on over priced hardware....

Why wouldnt they if all of the above turned out to be true?
I think if what OP says come to be true, most 3rd party would support the NX.

I think at launch you would see 3rd parties there, hopeing that NX takes off and their game becomes something first buyers of the console grab as well.

I guess they could be turned away, if even after they port stuff it still doesnt sell on the NX (nintendo owners prefer nintendo titles).

But Im pretty sure 3rd parties will give it a shot to prove it self.

If it's easy to include the NX console in the multiplatform development (so PC/PS4/XBO/NX development ain't much more hassle than PC/PS4/XBO without NX) and ports of 2013 - 2016 titles are unproblematic, third parties will support it. But don't expect dozens of NX-exclusives from them.

If these third party games are profitable enough on NX and are accepted by the NX-community (instead of just buying Nintendo's first party games), the third party developers will stay.

You're forgetting the key factor in whether the NX gets support or not. It cannot, and I mean CANNOT, have a gimmick. If third party devs need to alter the way a game plays to allow it to work on the console it's dead the moment they announce it.

That's it. They make it easy for devs to port their games and there's a good chance they'll be on board. There are still tings that could go wrong, but if they don't, they might as well not even bother with the rest. Just make whatever they want and hope they don't sell less than the Wii U.

At first probably, to test the waters. But if it winds up as more of the same then it'll fall back into the status quo.

Ubisoft will support it at launch, because they basically support everything at launch.

Activision will support it, because many of their franchises require a successful console among younger audiences and more casual gamers (Sylanders for instance).

EA will support it, because I believe they're legally obligated to port certain games (Madden for instance) to all viable consoles, and they'd need to try at least one to prove it is not viable.

Disney Interactive will because their games do about as well on Wii U as they do on XBone4.

WB Interactive will, because the Lego games sell fairly well on the Wii U, and sold like crazy on Wii.

Sega will based on their relationship with Nintendo.

Namco might or might not. They've worked with Nintendo on a few things, but haven't been huge supporters of the Wii U. Ditto for Capcom.

Bethesda is unlikely as they've just never worked with Nintendo. Same for Rockstar and many other western devs.

No, it has to have a gimmick, because if it's essentially the same as the already successful PS4, there is no market for it.
