Read Miyamoto's post above. They didn't say they were excited about Wii U and NBA2k14 was not on Wii U so your entire post is false.

Nintendo really needs to help promote 3rd party games period.  Playstation and Xbox do this a lot, using 3rd party games in sizzle reel ads.  Nintendo can't just focus the messaging on 1st party exclusives.  If they communicate Switch is purely a Nintendo box, that's what people will treat it as.

As for these statements, proximity to release is a key difference between switch and Wii U.  The Wii U had some good initial buzz, but the vast majority of that was in 2011.  By 2012, nearly every third party had gone silent or changed their tune to critical and skeptical.  We can't be sure why, some rumors suggest the first dev kits were stronger than the final ones, maybe some early PS4 and Xbone dev kits were out and about and those hurt the Wii U's support or maybe it was a lack of effort to effectively sell the device by Nintendo.  All this positivity about the Switch is coming out mere months before launch.  The final dev kits are out, the PS4, Xbone, and Pro are all in devs hands, all the necessary excuses to blow of the Switch are there if they were sufficient for it. 

They didn't said anything about Nintendo 3rd party effort, and now with Switch they specified said: "The folks at Nintendo are making a great effort to support third-party developers".

But having a second console solves all these issues.

3DS still had perfectly good engines for more Metal Gear, Tekken, Ridge Racer, Street Fighter, FIFA, Madden, etc. games ... none of those developers bothered, even the many of the Japanese devs and I don't think Switch will sell even as well as the 3DS. So we'll see. 

Nintendo fans need to start actually buying some third party content too, this is part of the problem. I will buy NBA 2K because I actually like sports games, but the rest of the Switch fan base ... lol, I doubt it. 

With the Wii U it was a lot of bitching and crying when games ran like 5 fps slower than the PS3/360 and that was the justification for not supporting games, well guess what? Switch is not going to be parity either. It's weaker hardware. People better support these games or they're not going to get more or them. That's just the bottom line. 

People saying this is the same as Wii U. You may want to research first.

Strauss Zelnick (TT CEO) on the Wii U

While Take-Two will make sports and family titles for the Wii U, its bigger core franchises have been notably absent from the list of partners. And that seems unlikely to change anytime soon.

"We haven't announced anything," says Zelnick on the possibility of moving the company's mature titles onto the Wii U. "I'm skeptical."

Deja Vu

Read the post above yours.

People need to accept that switch is getting a bigger positive reception, biggest positive reception for a Nintendo console since, since a lot of time. Not the same scenario of the wii u or wii where we had a lot of third parties talking crap about those consoles. If the support is there, we don't know yet, but you can't say "same thing was said about the wiiu" if you go back in time you will find a lot of dubious and bitter comments from developers, and a lot of "wtf is going" articles from the gaming media.

Being "very very excited" is totally different than praising a console directly. If somebody from Bethesda says that Switch was the best demo they've ever seen at E3, and they've stayed exclusive to PS, XB, and PC for some time and all of a sudden they praise a Nintendo console of all things, something is being said about Switch. We can't just say, "oh they said the same thing" when it wasn't the same thing or same situation.
