There's no point where I would have to admit that I am wrong.
In regards to the question of generations, you've said that it's not definitive yet, so even by your logic Switch might be considered gen 9 eventually when its lifecycle is long enough.
Righto you are but for now the Switch is firmly joining the 8th generation ...
In regards to Switch not competing in the home console market, you've been unable to provide proof for your claim. You like to refer to Switch as a handheld, but it's a $300 console with $60 games, both values being far above the typical prices of handhelds in the past. How do you explain why it sells so well?
Pricing and system design are not mutually exclusive. For example, TurboExpress by NEC and N-Gage by Nokia both launched at $299 USD ...
As for why Switch is successful at that price point, you forget about inflation. Consumers typically do not keep the same pricing expectations for everything over time and that especially applies to electronics such as game consoles. Either Sony or Microsoft will come out successful regardless of a potential $499 USD launch price tag and I imagine that Nintendo will bump the price of their Switch successor by another $50 to a total of $349 USD ...
In regards to the blue ocean point, you have argued based on the assumption that the Switch has no part in the home console market and must be viewed only in a handheld context, hence why you keep saying monopoly, but ignore the new value proposition of home console games being able to be played on the go on a whim; a value that puts Switch both in the home console and handheld market. What you need for this point is the proof that Switch is not competing in the home console market, but you don't have it.
It's "new value proposition" doesn't seem to change the Switch's sales curve all that much since it's performing close enough to the 3DS which was nearly a monopoly back then as well. The Sega Nomad offered a similar concept to the Switch by being able to play "home console games" (whatever that means) on the go as well ... (both sound practically identical in terms of feature set on the high level)
A portable console being able to play "home console games" (meaningless qualifier) is not a feature unique to the Switch ...
Your argument of a "unique value proposition" in case of the Switch has NO real meaning since you have yet to truly differentiate between "home console games" and "portable console games" ... (just calling Switch games as "home console games" is not good enough to establish that the Switch is in direct competition to the PS4/X1 which are true home console designs in the sense of the definition)
1. Indeed, I am right. Grouping Switch gen 8 is premature, especially because Switch is trending for a long lifespan.
2. Handhelds that launched at $300 and failed don't work as a way to argue that Switch is a handheld.
Inflation can't be a factor when all previous handhelds had to be priced below $200 to gain real traction. Switch is selling better at $300 than handhelds did at $200, plus the game prices went up significantly as well, from previously $40 to $60. A 33% increase in price in both areas from one generation to the next (or as you argue, within the same generation) can't be pinned down on inflation.
3. You are using the same fallacy that you've used in previous years. You think that Switch and the 3DS are performing similarly, but as usual you ignore the context. Switch is outpacing the 3DS despite the latter having a significant price drop and a revision during the same timeframe. This fallacy has been explained to you in 2017, you didn't want to believe it, time proved you wrong. This fallacy has been explained to you in 2018, you still didn't want to believe it, time proved you wrong again. And given what the actual sales trajectory is, you will be proven wrong in 2019 again. It's utterly predictable.
The Nomad isn't similar to Switch. Remember, when the topic of value proposition first came up, I said that Switch allows consumers to play home console games on the go while those games are still new; that's the differentiating factor of Switch. The Nomad and Turbo Express played games that were several years old and the market didn't care about that. You might as well say that the 3DS is similar to Switch because of Ocarina of Time 3D, but there's a huge difference between playing an old home console game on a portable console or being able to play Breath of the Wild that way from day 1. I am curious if you proceed to argue that Breath of the Wild can't be considered a home console game; if you are going to proceed to call the likes of Super Mario Odyssey, Splatoon 2 and Xenoblade Chronicles 2 handheld games.
It's ridiculously easy to determine whether Switch is a home console that can go portable or a handheld that connects to the TV. All one has to do is look at the console-defining games. Those titles have the scale of home console games and they play like what people have come to expect from home console games.
That's why it all comes down to one single question that you can answer with a 'yes' or 'no': Is Breath of the Wild a home console game?
