I mean in terms of droughts. Nintendo banked way too much NSMWU, who could blame them, most thought the same, the wii game was a monster in terms of sales. third party support was very good, but much better then anything before SNES.

Yeah, it is true they banked too hard on NSMBU, and they also undermined it by releasing NSMB2 just months earlier, so people had just gotten their fix and didn't wanna buy a crappy $300 system for another dose right afterwards.

But the third party support ultimately didn't matter; nobody had any reason to buy a Wii U for inferior versions of the same games they could get on the PS3/360 they already owned. So its short-lived third party support had no system selling power.

So Wii U ultimately didn't get any system selling software until it had been out long enough to have earned a reputation in the eyes of the mass market as a failed system with no games. 

The Switch, on the other hand, is a totally different story. It exploded out of the gate with the killer app of BOTW and followed up with further megatons like Splatoon 2 and Odyssey within the following 8 months. Software wise, Switch's output is far superior to Wii U.

Arguably, I don't think Switch has had much of software droughts. For the most part, the Switch has had multiple smaller games release on almost a weekly basis. And tbh, a month or two of no big first party games is nothing compared to the Wii U's first party timeline.

Some will say the first half of 2019 is not great for Nintendo's first party output, but I think it's been passable. January was NSMBUD, which sold beyond even most people's expectations. March was Yoshi's Crafted World, which appears to have good legs so far. June will soon have SMM2. Then you had smaller first party titles like Box Boy! + Box Girl! and Tetris 99.

Its far superior because it took wii u games. You are also forgetting mario kart 8 delux which is massive. Nobody is saying switch doesn't have a better lineup, it obviously does, but even if wiiu line up was better it was a console nobody desired. I mean all you have to do, is look at sales within 2 months it was selling like a dead console. even if it had mario kart it's first 8 months, i don't think results would have changed much WIIU was dead 2 months after arrival.

I think pretty much everybody agrees the Wii U was unappealing, horribly designed hardware.

All we're saying is that Switch's success is inextricably bound to its strong output of megaton software.

Well i been trying to say both the desired hardware and software is required to sell the way switch is selling in japan. Switch for example would have been  Successful regardless, if it only had one killer app, or 3 the first 8 months, maybe they would have to cut the price, or it would have sold 1 million less but it wouldn't be selling like a dead console.

Both are required, yes, but if Switch's software output had been as awful as Wii U's it would not have sold even half as well as it has.

Having 3 killer apps in the first 8 months and near constant support vs 1 in the first 12 months with crippling droughts makes a huge difference. 

I don't agree, I can diffidently see at least doing 6 million with Wii U line up.

With only 1 real system seller in its entire first year and an almost complete drought for the 11 months leading up to it? No matter how good the hardware is, no system is gonna sell great with support that weak, not even a portable in Japan.

Well i was comparing the first 2 years. I think Mario 3d world, Mario kart 8, and Smash, would have did the job. I can also see ZELDA HD, dragon quest x, and pikmen 3 doing much better, and helping momentum.
