Switch Sports would be very welcome by me. I think Nintendo made a big mistake not putting this (not this half-assed remake of the original Wii-Sports which was sold for each game separately) on WiiU. I think they wanted to deemphasize the Wiimote. But with Switch they focused in presentation much on the Joycons. I think a Wii Sports Resort like game might do very well. Let's see how Just Dance 2018 does.

I honestly don't think casuals are what's making the Switch sell and without them, those Sports titles won't sell. 

Not currently. But would be in line with this increased production. Switch has very well the selling points of the Wii built in in the hardware. So far they do not capitalize on it. 1-2-Switch in my opinion similar to Nintendoland not a real mover, only an addition. And look, even 1-2-Switch sells much more than a million.

Well than you can say same thing for most Nintendo IPs, Kirby, 2D/3D Mario, Mario Kart, Smash Bros, Animal Crossing, Splatoon..

Its not speculation, Nintendo itself said they intend to enter China market, and they actually said they cant do that alone (because China rules) so they need some local partner and they are actively looking for one.

None of those games are really geared towards kids/casuals. The only game from the list you can make a case for is 2D Mario.

True, but the announcing Wii Sports will bring some of the casuals who have nostalgia back in. 2-3m could easily happen.

What the fuck? Animal Crossing, Kirby, and Mario Kart aren't geared for kids or casuals? Even 3D Mario could be considered as such. And Splatoon and Smash are about even with demographics

When Nintendo says they want to expand the Switch into casual territory, I think they mean so with games that sell gangbusters. Yoshi and Kirby are casual, but they also don't sell a whole lot, so I don't think that's what Nintendo means.

Those games are geared towards everyone in general I would say. all the way from kids, to serious gamers. Not specifically targeting kids/casuals tho.

That's kind of a bad point though, don't you think? Nearly every Nintendo franchise sells to a diverse cast of demographics, that's why a "niche" franchise for Nintendo is 2-3 million and some of their competitors have front runner franchises that sell 2-3m. Nintendo franchises almost always cater to everyone possible, it just doesn't always lead to big sales. Their are exceptions, but Kirby and Animal Crossing and Mario Kart aren't them ... 

And I'm not going to make a bet on who Nintendo thinks Kirby and Animal Crossing and Mario Kart are for, but remember this is the same company who for years considered one of their most hardcore franchises as nothing but a "party game" (Ok yeah yeah it's technically Sakurai but you get my point)

Disagree, I dont see how Yoshi can be geared towards kids/casuals and games like Kirby, 3D Mario, Animal Crossing, Smash Bros, Mario Kart, Spaltoon...are not.

Its same thing with Yoshi also, I am surprised you fail to see that.
