Yeah I'm not seeing the Wii U comparison, the first 7 months of Wii U saw only Nintendoland and NSMBU from a first party perspective, while in that same timeframe Switch 2 got MK World, DK Bananza, Kirby Air Riders, Hyrule Warriors, Pokémon Legends Z-A, Prime 4, Drag x Drive...

They do both have a bunch of AAA third party ports, but where those dried up pretty fast for Wii U, there's no sign of them slowing down on Switch 2, on the contrary third party support is accelerating.

Was going to reply but basically this.

There's no way the way the Wii U happened was strategy. There is no way they intentionally made their lineup that shitty. And there is also no way they thought that the third party support, mostly ports of already dates games, would fill the gap.

What is more likely is that they struggled with shifting to HD, and their release schedule got fucked. Plus they were also supporting the 3ds which also got off to a rocky start.

Not that the name and gimmick weren't problems, but I still feel that the games lineup was the worst problem. If the system had BOTW, Mario Maker, and Splatoon within year one, I think the thing could have been just a flop instead of a disaster. 

Spot on, pretty much this.

Developing games across 4 systems in 2010/2011 (Wii, DS, Wii U, 3DS) plus transitioning to HD overwhelmed Nintendo's development capacity and choked their software output, leading to long gaps between releases, which killed any momentum Wii U had. For the whole first half of 2013 it got almost literally nothing and gained a reputation as a console with "no games" that it was never able to shake.

Nintendo ultimately chose to sacrifice Wii U to shore up 3DS, and moved on to Switch as soon as they could.

Yet another mistake they learned from the Wii U - Having a stronger Year 1 first party lineup.

If this were 2012 Nintendo, they would have gone the first 7 months with NS2 Welcome Tour and DK Bananza and called it a day. And they and the Pokemon Co. probably would have kept Pokemon Legends Z-A as a Switch 1 exclusive like how they kept Black/White 2 on the DS despite the 3DS already being out for a year.

So, then... they are not following the Wii U "strategy" at all?

The strategy was a good one, it's the execution that was God Awful.
