¿Porque no los dos?

Virtual Boy The 3DS is the closest to that. A lot of people consider it a success, though.

i wont be buying switch after the wii and wiiu im done with nintendo.

the switch will sell well initially as all nintendo fans will rush out and buy one, once dist settles it will be behind the ps4 and x1

Pretty much the one gaming/business blogger who predicted Wii's success is currently predicting similar success for Switch - and he also predicted failure for the Wii U.. Take it for what it's worth.

It's tough to judge success off some hype and preorders. We'll of course need several months to see how things hold up. But what I can say with certainty is this the most hyped I've been for a Nintendo console since the Wii, and I didn't much care for the Wii U.

Just as real as the hate it gets on the internet, so yeah, pretty real.

From all the hate Nintendo and the Switch seem to get on the internet from fanboys and clickbait sites/youtubers it feels like there's more hope for it to fail than hope for it to succeed.

I would say both

There is definitely hype going with the Switch, but I am also hoping it will do well

As is always the case for Nintendo.  In the Wii generation it succeeded in spite of this, but in the WiiU generation that hate stuck.  We'll see this time around, but I'm assuming with the handheld and console Nintendo fanbases joining forces that nothing will stop this console from at least beating the Gamecube's LTD.  That will be a huge bounce back after the WiiU.

Both those answers are correct and don't cancel each other out

The reason that nintendo fans putting their money behind the switch launch to help it succeed applies to the switch more so than the Wii U is the simple fact that the Wii U was coming off the success of the Wii, so you have a sense of complacency,  where as with the switch you can argue that nintendo stalwarts are  making sure that the switch gets off to a great  start, so that's why you can make that case.

Now my way of thinking is even though you can make a case for fans assuring it's early success , it is more complex than that,  the Switch by it's very  design immediatly muddies the water, so questions like who is getting onboard is just as important as why , it opens many more questions than answers,  like who is  driving the launch pre-orders is it WiiU owners or are the majority of what is a much larger group, 3DS owners who don't own a Wii U coming on board ,all this and how it effects people who up to now have chosen to use either Sony or MS for their console gaming and the 3DS for handheld, also is it exciting the casual market, there are many more questions like these,  so my conclusion is these broader demographics are making a larger impact than those with a pro Nintendo agenda deliberately choosing to buy early success .
