According to VGC, the Switch sold around 1.5m more units than it has shipped during the first six months of the year. It's probably slightly overtracked, eithery way, but the main factor seems to be they heavily stuffed the channel last holidays and had far more units in the distribution channel than usual throughout most of the first semester.

at this point Nintendo would be wasting MK9 on the Switch as it would help the Switch 2 at launch. I honestly don't feel the need for it as I keep playing MK8

You're right. No way MK9 is going to happen on Switch when MK8 is selling so much. We've never seen a console with 2 Mario Kart games, and I don't think we ever will.

If NS is d0m3d, as every Ninty product is, it's quite a fat d0m3.

MK9 at launch would be an awesome move. 

How people can use Nintendo's amazing First Party sales as a negative is always beyond me.  Nintendo's games aren't cannibalizing the market.  People play a lot of games, and there are many, many 3rd Party success stories on the Switch.  But the fact is is that Nintendo is the best developer in all of gaming.  Their titles are long lasting and end up being staples for generations to come.  I'm definitely not saying that Sony fans don't prefer Sony games more, or the same with Microsoft, but you can't deny just how solid the "average" Nintendo game is when it releases.  They often feature very simple mechanics, few requirements to upgrade to a DLC package, and the depth to keep people playing for hundreds of hours.  Nintendo doesn't "have work to do in other areas."  Other developers have work to do in those areas.  Nintendo created the architecture to port and produce games very easily.  They've built a userbase that is as healthy as any of the best from each generation.  Their system has shown that it can make the Switch version of titles exceed the sales on other consoles.  And they've even had wiiiiide open release schedules where their own titles weren't competing head on with 3rd party competition.  To me, the onus is on the 3rd Party developers to step up to the plate and deliver the Switch fanbase compelling and magical titles that can rival the style and charm of their Nintendo counterparts.

I don't come to these forums much anymore, but it does make me feel good seeing this thread's title after all those threads from two years ago insisting that switch would flop harder than wiiu and/or not get to 30 million units

But have we ever seen a home console (except the NES), without its own MK exclusive ?

We've never seen a home console with a MK Remaster either. Which is the reason it won't have an "MK Exclusive".

If we're going to see another Kart racer on Switch it'll be a Diddy Kong Racing reboot. But I don't think that's going to happen.

"Nintendo games are selling way better than 3rd party games on switch".
You don't say. Most 3rd party would absolutely love to get a quarter LT sales of a single flagship Nintendo title (across all platforms).
