The Switch will absolutely not fall between 155-160 million, especially with the recent statements of Bowser.(the most recent quarterly report has it at 150.86 million already)
Switch 1 will fall anywhere between 170-180 million. It will be produced for a few more years at least. It will be the cheaper alternative for Nintendo.
If Nintendo really wanted to get to the 170-180m range, I don't think it'd be that difficult for them. They could lower the price, introduce new models or special editions, offer some nice bundles, keep it in production for 4 more years, etc. I just don't think they're going to do much of any of that. I guess we'll see.
Took away the old games. This lineup seems good for the first year of a console. I still think we are going to get a megaton but even if we don't, it's a good lineup. It's much better than what we got from Sony and Microsoft in the first year of their consoles (and in MS' case like the first three years). You can't just wave away a game because it is "NS1 game" via declaration. People will play it for Switch 2, just like poeple played God of War Ragnarok or GT7 on PS5 and they are unequivocally PS5 games.
What would be a hot lineup to you?
The PS5 pre-launch showcase was pretty misleading. I remember how pumped this board was about how great the launch window was going to be, but it was mostly smoke and mirrors.

I know people are annoyed that Nintendo seemed to focus almost exclusively on the 2025 pipeline, but at least people buying at launch are under no delusion about what they'll actually be playing in the first year.
