There's plenty of amazing third party games coming to Nintendo Switch. I could care less about their supposed size though. 

Shovel Knight and Sonic Mania are some of the best games I've played this year. I bet you they're selling incredibly well on the Nintendo Switch. 

There's also NBA2K18, Fifa 18, Skyrim, Dragon Quest XI, etc. for those who care. More will surely come in the future. 

I hear ya, but thats modest compared to Xbox, PS4, and PC.

Some of that support may away as well looking at trends.

I still can't believe this was even a thing. lol

But the forum dwellers told me they were! After all, average message board dwellers always know better than a multibillion dollar company that has been in the game for over 30 years when it comes to gaming and like 150 years as a company..

Contrary to belief that these giant brands are fighting each other, that simply isn't their bussiness. They share the same currency If one is having a bad stake in the market share, then the other will feel it aswell. They have a respect, working along side each other and if one were in dire straights, the other would help them out now. That might not of been entirely the case before, but they've grown up much realizing they are big enough now and see clearly they need each other. Both of them make Japan. Take one away and the other would be left holding the world on it's shoulder. 

Nintendo were never doomed... but they sure were on that road.

Nintendo is developing games based on their IPs, for the first time ever, on iOS and Android. Why? Because the pressure of investors and a failing console was too much for them to handle. So, they gave in.
It wasn't the money in the bank that made investors relax.
That old idea that Nintendo has enough money to develop a few more failures, it's just that, a nice, comforting idea.

Wii U was an absolute failure. 3DS, despite doing respectable numbers, when compared to the likes of DS and GBA, not only does it look bad, it shows that those days are over for Nintendo - bar a new DS/Wii like feature.

Switch might be doing great, but that's not enough to spell success.
For now it's selling on 3/4 system sellers and a really cool concept. But what about a year or two from now?

Also, what if Nintendo never develops a 3DS successor?
All pressure will lie on Switch. And Nintendo is known for failing in the segment.

Every single one of your points is completely illogical.

1.) 3DS sales were up (and are still up) in the period after Nintendo started making mobile games. So, rather than replacing it, mobile has actually improved Nintendo's console business, which is exactly what they stated as the purpose of developing mobile games.

2.) 3DS has sold vastly more first-party software than the GBA. Nintendo would gladly trade 9 million in console sales for 90 million in software sales.

3.) Two years from now, Nintendo will have released a dozen new games. You know, just like every other console that has ever existed. Do you think Nintendo is just going to stop making games after this year or something?

4.) The Switch is a 3DS successor. Nintendo is not known for failing in the handheld market. You're trying to spin this as some sort of negative, when in reality, the Switch benefits greatly from being the only Nintendo console going forward. Now their home-console masterpieces like Breath of the Wild and Super Mario Odyssey are on the same platform as their immensely popular handheld IPs like Pokémon and Animal Crossing.

I'm pretty sure if the Switch failed, it would have been the end of Nintendo, read they wouldn't have had the money to recoup the costs of R&D.

Also, I'm pretty sure going mobile was the reason their stocks jumped so much, it was pretty much ALL mobile news. Pokemon (and other mobile games) saved Nintendo.

I'm sorry to be rude, and I actually don't mean to be rude, but you obviously don't read financial reports. Therefore, your sentiment is factually wrong.

Well I'm not sure about the R&D thing, but if you got evidence go ahead and post it but the thing about mobile is 100%.
