With online is a 10 million seller confirmed.

What? That doesn't make any sense. The reason the original wii sports is so ridiculously popular among non-traditional gamers is that it's easy to play. Adding an online element would complicate it and take away the only thing Wii Sports had going for it.

I think they have at least a 5 million seller based solely on the name "Wii Sports", and that's solely with non-traditionals.

Traditional gamers (who own wiis, although we are few and far between) will buy this game because we want to play with the wii motion plus, so that might add another million or two. And that's before any hype, or even finding out if the game is any fun!

Online would be great with WiiSpeak for swordfighting.

I would think they wasted disc space and development time.

a must buy

It's not like they would be forced to play online ...

No, but it changes the paradigm of how people talk about the game. If it had online it would appeal to traditional gamers, who would go on at length at how awesome playing on the internet is, and non-traditional gamers would hear that and think 'Eww... That sounds complicated'. By keeping it firmly in the realm of the non-traditional gamers, the word of mouth will spread the same way it did for the wii originally: people playing with their friends, people seeing famous people on morning shows and talk shows play it, ect.

Any 'hardcore' gamers who read that and get offended by that, well, Stop! The Wii Sports (and for that matter the entire Wii series) was never about the traditional gamers.

I wouldn't be too surprised if it had limited online play, though I'd only use it if there were online sword tournaments

 You talk as if casual gamers (whatever that means) are retarded.  Don't they have PCs in their homes?  Don't they know how to operate televisions, microwaves, dvd players, etc?  Or are they half brains that only know how to put Wii Sports into the Wii and do nothing else on this earth? If they can go online with their PCs what could be so difficult about going online with Wii?   

I'm not saying that at all. However, it's a value judgement for most people: Is doing X worth the reward Y. Now, the X is relatively small: Reading a manual, figuring out how their wireless network is encrypted. My dad loves Wii Sports, but he's not going to find out the 16 character random password I set up on his wireless. Unlike traditional gamers, non-traditional gamers aren't neccessarily geeks. They're just as likely to be soccer moms who throw up their hands at the very idea of a WEP encryption or a wireless LAN. The key issue in the value judgement, however, is the reward Y. Will Joe and Jill Non-Traditional Gamer, who play Wii Sports every night, who bought Wii Fit and Mario Kart Wii to have fun with their teenage kids and get more exercise, be excited by the idea of playing a video game against people they never met? Of course not. The entire mystique of the wii is that it brings people, and families, together, which is not what you're doing if you're at different ends of an internet connection.

Furthermore, non-traditional (note I never said 'casual') gamers feel estranged from the entire traditional gaming hierarchy. They aren't too stupid to play Halo 3, they just think the endevour isn't worth getting the hang of the hostile controls. In the same way, I think if you ask a lot of new 'wii sports' gamers about online play, they'll say something along the lines of "Isn't that for sweaty nerds who live in their moms basement?" I'm not saying this is true, but that's the perception a lot of people have.

You know that oft repeated meme of the VCR/DVD clock that is constantly blinking 12:00 because nobody bothered to set it? That's not because nobody is smart enough to set it, it's because nobody cares if they have a clock on their VCR.
