as a switch owner, no interest.

they will not do mario kart numbers. i just dont see it.

Mk was a port. A glorious one, but a port. Smash is a brand new game with a ton of new characters, balances, maps, and a campaign mode. It even has "Ultimate" as a subtitle, making it just sounds cool. Also, MK 8 being a port and releasing  so soon, there is a pretty big chance we will see another racer on the switch, like Diddy Kong racing, that cannibalizes sales of MK.

I think it will sell more than MK, not sure about 25 mil though.

Just a heads up MK8D is close to 12mil. This Q will probably be its biggest excluding launch since switch will be doong extremly well and mk8 is this years attractive bundle. I can see it getting close to 15mil by years end.

If no new mk comes out soon itll do 20mil+ lifetime. Maybe over 25mil

Disagree, even though MK8D is a port, it's just got a lot wider appeal. The Fighting genre just doesn't appeal to as wide an audience. Even though Smash Bros is more palatable to people who don't usually like fighting games (me).

I don't think Smash will outsell MK8D lifetime. Mario Kart will have much longer legs imo.

I will agree with you if no new MK comes out PLUS no new other big racer from Nintendo. If DKR comes out or something else, I think we will see a dropoff in MK sales.

To expand on my comment about Smash not having the legs of Mario Kart, here's comparing the legs for the Wii, 3DS and WiiU entries in these series. Lower First Year % means stronger legs.

These are retail only sales, as you can see Mario Kart typically has the majority of it's sales outside it's first year of release, whereas Smash Bros has the majority of sales within it's first 52 weeks on sale. This is because Mario Kart has a much wider appeal towards the more casual gamer, as such it sells to new people picking up the system for a long time. Whereas the majority of people interested in Smash Bros lean more to the hardcore, and are very likely to already own the system, or purchase the system specifically for Smash relatively soon after it's release

The WiiU releases are a lot closer when it comes to legs, though this can be explained by the WiiU being brutally murdered.

Taking an average from these 3 games in each series, Smash Bros has 72.1% of it's lifetime sales in it's first 52 weeks, while Mario Kart has only 49.4%.

Yes let’s completely disregard the growing esport scene surrounding smash since the release of BRAWL.

Mario Kart is a franchise that has already peaked in sales (unless 8 Deluxe prove me wrong)

Smash has yet to peak. We don’t know the limit of that franchise like we know of Pokémon or Mario Kart.

If Nintendo can get Smash big in places like South Korea... I see no reason as too why it won't be able to match MK8D.

Mario Kart 8 D will definitely outsell Smash. However I expect Mario Kart to sell 40m-50m. Therefore it's possible for Smash to still do 25m+

Err... Calm down son! Mario Kart isn't getting close to 40m. 25m max.
