It can, but I'm not sure where the LT for the Switch will be atm

First off, that saying doesnt work all the time. Just look at the Dreamcast. It had an exceptional library for a console that was on sale for one and a half year. Jet Set Radio, Shenmue, Sonic Adventure, NBA 2k, soul calibur, crazy taxi, and more.

Super Smash Bros 4 is widely regarded as better than Brawl and the original. DKCTF  was on par with its predecessors well, the backlash to that game only came because people were pissed retro made another donkey kong instead of doing something else. Captain toad is regarded as an underrated gem. As much as I dont like super mario 3d world, it still got a 93 METACRITIC. Shows that critics and audience alike still liked the game.

As for animal crossing, the decision to make one for the 3DS instead of Wii U was right because Wild World outsold City folk and the original like 3:1.

Zelda had a game come out in 2011, so it was obvious that a 2012 release for next zelda was unreasonable.

But you are right to an extent. Animal crossing amiibo festival, star fox zero, mario party 10, wii party U, mario tennis ultra smash, paper mario color splash, nintendo land and more were underwhelming.

But it cant be argued that the main cause of the failure of WiiU was the console itself. Terrible tablet gimmick controller, teriible and non-existent marketing, terrible name, the list goes on and on.

And sony's victory over microsoft was mostly cause of the drm blunder and higher price of the xbox one. The excusives were just a supporting cause.

Dreamcast had nearly nothing, it's library was anything but "exceptional" aside from the reviewer/critic perspective ... (if the customers weren't convinced then that's all that mattered) 

SSB4 was about equal as far as critics go compared with SSB Brawl but that stops right there since there were much more who was convinced of the quality of the latter ... 

DKCTF obviously wasn't as good as it's predecessor, Captain Toad deserves it's rating as is and SM3DW just wasn't as good as SMG so all of these things factored into WII U's suffering hardware sales and when you don't convince your customers that's exactly what will happen ... 

WII U's hardware sales was more than warranted given the shit effort that Nintendo went through with it. Nintendo making SSB for WII U and not for Animal Crossing despite the fact that both would've sold more on their handheld counterparts was an amateur's mistakes but then you ignore the biggest elephant in the room which is the absence of the Wii franchise ... (Nobody let down the WII U down other than Nintendo themselves!)

The always online DRM was fixed before launch and the price was fixed shorty thereafter but did their sales ever equalize ? Nope, the only explanation for that is because Sony somehow convinced it's customer base that it had a better library than the competitor and that's despite Microsoft's more aggressive deals ... 

This is getting off-topic anyways so let's leave it at that ... 

You are way oversimplifying.

A console needs high quality software, a steady output of software and a wide variety of software.

Outside of software there is also hardware features & design, marketing/advertising, price.

A console needs to hit all or most of these things in order to be a mainstream success, so far Switch has all of them while Wii U was missing almost all of them.

So hes right, you cant use the lame excuse of, "those games didnt sell Wii U so would why they sell Switch?"

Hardware features didn't help the PS3 from being clobbered by it's competition and marketing/advertising couldn't save the Vita from being a catastrophe despite having the Playstation branding which is arguably the strongest console brand ... 

Out all of the points the only one I can agree with is price but even then that can be fixed with software or doing a price cut itself so yes for the most part it is indeed games that will sell the hardware itself and we keep seeing this pattern across multiple industries so don't around projecting it as a lame excuse ... 

When it comes to digital media people don't care about the functionality, they care about the content ... 

it will be visible by next year. if it continues sales. probably (as it will have more years in its life). if the sales dip. probably not.

historically speaking nintendo consoles sales are very frontloaded. well. all consoles are frontloaded. but nintendos are usually more.

sorry but i dont think this will happen because the switch dont will have this long lifetime

Probably it can. Though it will take a long time.

I hate it when people do what you just did.

When somebody gives a list of things and says that all of them combined are required, you cant just isolate one point.

I said software (quality/output/variety), hardware (design/features/specs), marketing/advertising & price need to all come together to make a console appealing.

I know the hardware features of PS3 didnt help it early on, thats because the price was higher than people were willing to pay, the software was arguably worse than the competitors and the marketing wasnt very good initially. As for Vita, it had shit marketing/advertising from the get go so i have no idea why you brought it up as a positive.

Having a great game every 3-4 months is not enough to make hardware succeed if the software output is slow, the hardware features are unappealing, the device is poorly designed, the marketing/advertising sucks and the price is high for what the product offers.

So yes, its a lame excuse to say, "this game didnt sell this console so why would it sell that console?" when there are multiple other factors at play.

of course, NA is Nintendo's highest selling territory.

Switch should reach at least 30m sales in NA. Which is about what XBO should finish it, give or take a a couple of million.
