First off, since the original Wii Sports is bundled with the Wii Id like to exclude it from this argument. I think that leaves Wii Fit and Mario Kart Wii as the other two contenders. I was looking at those games current sales numbers (20 million and 13 million), and they are both impressive. However, I think WSR has the potential to overtake them in lifetime sales. For one the game has a reasonably low price and comes packaged with Wii MotionPlus. Those alone are two incentives to get the game. 

Moreover, the game has a huge gamer install base since there are 45 million plus Wii Sports in circulation across the globe. It is safe to assume that people who have already played the first one would generally be more inclined to buy the second reiteration.

Third, as a first party game Nintendo has strongly backed it with a strong advertising campaign. It is also the premier title for the Wii MotionPlus technology.  Obviously, Nintendo has a lot of stake in this game and wants it to suceed to boost console sales and open up the Wii MotionPlus market.

Finally, I feel the game delivers. 12 sports with 30+ modes makes it a superb follow up to the already popular Wii Sports. Though it lacks online multiplayer and some other standard features like leaderboards, there is still enough content to satisfy any gamer who found the original enjoyable.

Reviews are not out yet but I expect the game to be well received, 80-90 out of a 100 on aggregate review sites. Anything less would be a surprise to me.

In any event fans have already shown their support for the game in Japan by forking over their hard earned yen. Next month other huge openings will certaintly follow.

So the question is will it be able to gain ground and eventually overtake titles that have come out before it?  And in that case would there be any other concievable title that could challenge it?

Over take WiiFit, not a chance in hell. Infact I doubt it will break the lifetime sales of MarioKart either. Now you can argue that similiar bundles like WiiFit and WiiPlay have both garnered huge sales, both titles had far more advantages then WiiSportsResort! What advantages?

WiiPlay for example, the second most successful title on the Wii debut at a time when a coontroller was hard to find. I remember I couldn't find controllers anywhere. I didn't want to buy WiiPlay but for ten extra dollars I decided I was willing to pay that to get another controller. I know many other people did the same thing. It was all over N-Sider (Nintendo's official forums). Hundreds of Nintendo hardcore fans were rushing to stores to buy WiiPlay so they could finally get a second controller. I know of people who bought three WiiPlays so that they had 4 controllers. WiiPlay sold out of nessecity and practicality not due to actual interest in the title.

WiiFit , launched in North America the most obese continent on the globe and found more success in the United States the most obese country on the globe soully because people want to loose weight with little effort. I remember reading in the news that many leading Gym's saw declines in membership when WiiFit was launched because people were wanting to pay less to get in shape. People would rather play a video game then work out in a gym. WiiFit sold largely to soccer moms and obese people wanting so much to be in thinner better shape. Nintendo was extremely smart to launch a fitness product. Also like WiiPlay the only way to get the Balance Board was to buy a copy of WiiFit, today the balance board isn't that supported but the hardware and the aspect of getting thin sold WiiFit.

MarioKart/SmashBros...etc...etc... These are Nintendo top tier games and Nintendo's most profitable franchises. It is possible that WiiSportsResort will ship upwards of eight mill it might beat out SmashBros may even pose a challenge to MarioKart but I highly doubt it will over take MarioKart and join the likes of WiiFit or WiiPlay. Beating Nintendo's name brands will be a big enough challenge! Of course as many pointed out WiiSports was bundled with every console so that will serve as superb advertising for WiiSportsResort. It may but not likely, as many have pointed out WiiSports only sold because it was bundled with the Wii hardware if it handn't been bundled it would have only sold a couple million copies.

So why will people pick up WiiSportsResort? A few die hard Nintendo fans will pick up WiiSportsResort and a few casual gamers will pick up WiiSportsResort. But Nintendo is bundling WiiMotionPlus with tons of games that should see big success least of which is RedSteel2 (Where I'll be getting WM+). The hardware factor is greatly effected because motion plus will be easy to find in stores and gamers won't be required to have WiiMotionPlus for anything other then a few titles (Unlike WiiPlay). So at best it could see sales up like WiiFit, but after you take the healthy living factor out and you remove the hardware dependability. You've got just another tech demo!

I think WiiSportsResort will ship a million copies month one, probubly ship another million copies this fall with another million copies next spring. But will taper off shortly after. It won't have legs. I'd say life long sales of around 5-8 million at best but at worst and more likely 3-4 million!

But as I said theirs no way in hell people will buy more copies of a cheaply developed Tech Demo then that of MarioKart. Its just not going to happen!

WSR will be a great seller due to the popularity of Wii Sports, over 10 mill. But it really can't surpass Wii Fit due to the insane lead it had.

No. WiiFit will rule them all.

WiiFit has been amazing that is certain, especially considering its price tag. But if you look at WSR and its much cheaper price I dont see why it cant enjoy the same success in the long term. It has already had an astounding debut in Japan. Perhaps Wii Fit has a daunting lead but WSR could finish up second in the race if not challenge the for the top selling title.

To those who doubt Wii Sports Resort it´s the same way some people doubted Wii Fit would be a huge hit two years ago. Actually I don´t think Wii Sport Resort is going to match Wii Fit sales (since Wii Fit will continue to sell fantastic) but I think WSR is a sure thing for sales of 10 million +. I´d say that at the very least it will beat Super Smash Bros Brawl.

I think it can beat Wii fit. Just you wait and see.

natal and scibblenauts will rule them all ooops did i say that out loud? :D

err i mean WSR will sell a truck load but i doubt i will beat wii fit and will struggle to overtake Mario Kart wii

No chance to beat Wii Fit, but it can sell 20 millions and more
