Looks like Japan is completely driven by Switch

At the end of its life the Switch will have sold at least 30 million units and the PS5 6-8 million. The PS2 sold 21 million units in Japan. If the PS5 sold that much, the 9th gen would have numbers way beyond 50 million. For the PS5 and Switch combined to sell less than 28 million units would need the Switch to stop selling in half a year. The market in Japan is performing as good, if not even better than before the Switch launched. I believe, that the Seitch has a chance at surpassing the total sales numbers of the Gameboy at 32.47 million and the DS at 32.99 million. It's only halfway through its life after all.

IcaroRibeiro, the Switch has this year surpassed the peak year of the 3DS in Japan in hardware sales, 2012. That says a lot. Next year has a chance at matching this years numbers of almost 6 million.

Well, Switch obviously is both, that is not so difficult a concept. Just as humans are both animals and bipeds. Things can be categorized multiple times, these categories often aren't mutually exclusive.

Switch is love, switch is life!

Also, who needs a handheld or home console market when you can have your cake and eat it too. The 9th gen really has so much potential. They are outselling 8th gen right outta the park.

Generation will more consoles has more sales than generation with fewer consoles. More at 11.

Joking aside, the problem with this assessment is you're not comparing apples to apples. Sure, let's say total Gen 9 consoles sales are less than Gen 8. But Gen 8 has more systems. This means someone could own a Wii U, a 3DS and a Vita in Gen 8 but they would just own a Switch in Gen 9. So there really wasn't a decline since that customer is still in the market and still buys systems and games. The best comparison would be to remove the Vita and Wii U since you can assume those customers should be absorbed into another system (or try and come up with a factor to reduce them). Or, as you mentioned, look at software as this should remain consistent (someone may buy multiple systems but probably wouldn't have bought multiple of the same title). Otherwise, right now it's a flawed analysis because we should expect the sales of 5 systems is greater than the sales of 3 systems. 

It's amazing that Ninty alone can manage the sales of previous gens without the help of any other company. I hope the switch reaches 30mil+ at least

Definitely still has some work to do! Japan definitely likes games, but you and I both know that many sales from Japan go to other countries like China.

However more consoles in the market means higher revenue from hardware units which means the market shrinking as far as hardware revenue is concerned 

I questioned whether having less systems in the market will lead to more software spending. If software revenue growth is big enough to cover the hardware loss, then the market is flat or growing. If it's not, then the market is declining

Ultimately, I don't think we can separate home and handled console markets anymore. Nintendo is the only company releasing dedicated handhelds, and their best selling model is a hybrid. What can be said however is home-exclusive consoles are failing to meet their past popularity, with Japanese customers choosing portable or hybrid models instead

This OP is full of sarcasm and shots fired in all directions and I love it!
