I've got nothing more to say. I usually do it because I agree with the comment. 

Okay, so the level of discourse in this entire topic has been atrocious. You asked for a fair amount of evidence that has been frequently refused. 

I could just say something like "It's pretty clear that the Switch has the potential of cannibalizing Sony sales. If you disagree, I look forward to your numbers that prove otherwise (since the burden of proof isnt on the person making the claim, right)." That's nonsense. How can you talk to that kind of statement?

If we want a higher level is discussion that isn't based on strawmen and vagaries, I'll help you out. I went through the MC thread looking at all of the cannibalism related pieces of discussion that happened before Kerotan started this echo chamber. Even if it didn't say the word 'cannibal,' but seemed kind of related, I posted it below:

Three people (including Kerotan) used this word before the thread was created. 

Three. 

Three does not make a myth. And one of them came in here and retracted the statement. 

That's absolutely not true. The only reason cannibalism didn't die after the first two people mentioned it was because you brought it up well after that discussion died. You have no proof to claim something as nonsensical as that. 

I look forward to your proof to back it up, though, at which point I'll gladly concede. 

But this time I'm not helping you.

Yep thats right. If sony is not making another Handheld or a Hybrid. How else can they compete with Nintendo. 

No

You are right Kerotan, the Switch is not eating into PS4 sales in Japan. As you pointed out last year saw Final Fantasy, the Pro, the Slim and a price cut. It's perfectly normal for sales to be down a bit and we don't even know yet how the PS4 will sell during the holiday season in Japan.

In general, pointing out "declining" sales shortly before the holiday period is useless anyways: Back during the PS3 vs 360 days the PS3 would win most of the year but then Microsoft had these awesome Christmas promotions and thanks to Black Friday and the holidays would pass PS3 yearly sales. Same applies here: A single week in late December can eradicate most of the decline in sales that has accumulated over the whole year - the holiday period is so important for yearly sales, it can't be stressed enough (think of the 3DS in 2011 or the original DS in 2005, which trailed behind the PSP for most of the year and then sold a freaking 600k units in a single week in Japan).

The Switch also doesn't seem to draw any software support from the PS4 in Japan. Some titles are multiplatform now but that's to be expected. The Switch is instead usurping PS Vita and 3DS support (which was also to be expected). So yes, I agree with your original post.

Three. 

Three does not make a myth. And one of them came in here and retracted the statement. 

The demographics for each platform are different, switch is popular with elementary to high schoolers, and small families, ps4 is popular with the highschool to college age kids, and young men, and because the latter demographic has much less free time than the former,the latter is less likely to buy a games console as they have much less time to enjoy it.

Ironically, psp, ds and 3ds seem to be the console of choice for business men who game, since they can do it during the work commute with relative ease, and the consoles themselves can be bought very cheaply pre-owned.

I have never seen anyone on their commute playing switch, it is most likely due to its size, it is not the sort of size that would be comfortable to play on a packed train.

You only really see young kids in the mall with them sat somewhere playing while thier parents do the shopping.

Back to the point, different demographics have different buying patterns and available time patterns, for example early in a year workflow is generally slow, with the days being longer people studying or working gave more time, where as kids and young teens generally make use of the time to play outside and hang out, but the closer to winter you get, the less available time college and university students have, there's exams, cramming, shorter days, businesses ramp up the workload in expectation of the holidays, (December is the most stressful month for workers in japan) where as kids are spending more time in the house bored because it's dark and cold out by 5pm, and schools out for Christmas, so they have much more time for things like gaming. 

So no, ps4 sales don't cut into switch, and switch sales don't cut into ps4
