I agree with Sean Malstrom, it won't work. Because it's something around the control and not the focus on an existing sports arcade mode, like Wii Sports. It is not a transposition that translates into an immersion activity by motion simulation. Remember more Kinect Adventures than Wii Sports.

This idea is much better than nintendo had. Integrate everything, including the motion control games you use. And launch a Switch Sports as well, such as new modalities and local and online game integration.

Looks a lot better than I thought it would. I'm not the target audience, but I'm happy it exists.

The presenters in the video though, I'm scared they're going to eat me in my sleep.

$80 for the game+ring+strap. Not that bad actually.

Gonna have to assume that's USD so I'll be looking at $100 CDN. That may be slightly out of range of what I want to pay. Maybe I can strike a deal on Amazon.

Can't we just get a new Wii Sports Resort instead? This doesn't seem to have a really clear audience...

I would very much like a Switch Sports Resort. This is really what Switch is missing currently.

So you think using Miis in a fitness party style game would suit that audience more than this?

are you seriously saying this is the most interesting switch game on the entire switch platform? Or just for the motion aspect of the system?

I am weirdly interested by this game.This is far more interesting than anything the series has seen.

Wow...color me impressed with where this ended up going. Kudos to Nintendo for getting us used to the whole ring/strap concept in the first place. I absolutely think that showing the peripheral and the game at the same time would have been too much info/wtf at the same time. Like others, I do fear that both of these concepts (fitness/adventure rpg) are going after a different audience, but I'm also intrigued whether there might be a few people who will find it an easy transition between the two. I sincerely doubt Nintendo needs to sell 5 million of these to make a profit. I think they'd be happy enough with 1-1.5 mil. And I'm definitely interested in seeing whatever follows this title.

edit....

There are even simple mini game modes and normal fitness routines.  Yeah, I just finished watching the video.  They could have easily inverted the presentation to focus more on the fit.  I do have a feeling in the future we will see a shorter commercial that almost doesn't mention the adventure mode.  This one seems like it's aimed at us particularly and is showing gamers how this could be a fun idea for them.

Also...October 18th!  Wow...Nintendo sure are great at keeping things under wrap.  This is almost a shadow drop.  It's like they've got their console division, handheld division, quirky peripheral division, and fitness division all working together to deliver nonstop new experiences.  I honestly don't think we have any concerns about droughts for this system.  The games might not always be what you want to play, but there will be a steady stream.
