I wasn't talking about 3rd party JRPGs like SMT since the bigger budget ones also somehow manage to be somewhat mainstream but even JRPGs on Nintendo handhelds in general are far away from being a slam dunk in terms of commercial performance if media create numbers for recent Switch ports are anything to go by ... 

Catherine is a quirky Japanese puzzle game which has a different target demographic compared to many of the other 3rd party games Japanese games that release on Nintendo systems. It's a puzzle game that's rated M which is a concept that doesn't get much more dissimilar than what the Nintendo audience is frequently used to ... 

All in all that's a fairly presumptuous statement your making especially late in this generation when the PS4 has already established itself as the incumbent for 3rd party Japanese games and it especially applies for smaller developers as well since they see the best commercial performance on PS4 rather than the Switch. Sony's grip on Japanese 3rd party games is only going to get tighter next year with releases such as AC7, KH3, GE3, DoA 6, Jump Force, DMC 5, One Piece, Sekiro and well you get the idea since PS4 won't be seeing a shortage of 3rd party Japanese games in general ...

Even in the case of Persona, how do you suppose that it's a realistic option for Atlus to demand their customers transition to another platform by shelling out $300 just because the studio wanted to solely change their lead platform when the previous platform they've served is approaching 100M units in the short term and currently sells more than the competitors annually ?

I don't think the two games are linked, but I also don't think there's anything in Catherine to censor. A lot of the content is more suggestive than shown. Persona 5 was already multiplat though, so I don't understand that part of the question either.

What games have been censored and in what way were the censored aspects similar to Catherine and Persona?  

1) JRPGs have been successful and relevant on Nintendo dating back to the NES. Pokemon, Final Fantasy, Dragon Quest, Monster Hunter, the Chrono series, Kingdom Hearts, just about every major JRPG franchise in the book has a history with being on Nintendo systems. 1-3 year old ports of 3rd party games that have already been out on PS4 during that time isn't exactly the most ideal comparison. 

2) Didn't seem to stop other M rated games like Doom, or Wolfenstein, or Skyrim from making it on the Switch, and from what I recall, Bethesda was pretty pleased with the performances of those games. It sure as hell didn't stop Bayonetta from virtually becoming an unofficial Nintendo franchise despite its much, over the top, M rated nature. Bayonetta as a character is at the point where she's pretty much blurring the lines between 1st and 3rd party character. That was a combination of Platinum's development and Nintendo's publishing and marketing that established that franchise as a valuable one for Nintendo. Bayonetta 3 is one of the more highly anticipated Switch games alongside some of Nintendo's own 1st party offerings. So, if Atlus and Nintendo really wanted to, they could make the same happen for Catherine and Persona.

3) Monster Hunter fans didn't seem to have a problem in the long run with Monster Hunter World moving to PlayStation, Xbox, and PC. And Capcom certainly isn't complaining at all with their choice of platforms for their 1st 10 million seller. As long as the game looks amazing and it has what they expect and are hoping for from the next mainline entry, fans will learn to move past it.
Furthermore, there was a 8 year gap between Persona 4 and Persona 5. Even if the wait for Persona 6 were 2 years shorter, that would put it at a 2022 release date. The PS4 will be mostly  obsolete by that point and the fans will have moved on and expecting Persona 6 to launch on a newer, more relevant system, which at that point, for a game like Persona, will be the PS5 and the Switch (or Switch 2, though I highly doubt Nintendo will give the Switch a shorter life span than the 3DS.) 
The PS5 will likely be the #1 selling system (if Sony doesn't royally fuck up their reveal and launch like they did with the PS3 and Microsoft did with the Xbox One), but it still won't have an install base yet to match the Switch, which should still be selling respectfully well at a much cheaper price point with an install base that's also closer to 100m. 

Is there any game censored so far that isn't an all age version of a 18+VN or Senran Kagura ?
Catherine is rated M so there is no reason to censor it.

I mean the PS4 is losing ground fast to the switch at this point, the only reason I see why most Japanese games are not multiplayer is because they've been in development for at least a couple years.

I don't think Persona will go anywhere. Catherine however, has a good possibility of being censored. Just looking at the recent situation I am convinced that theres attention to it at Sony's and Atlus's offices.

I think you are overeaching.Quite a bit.First of all, lets just say that PS is not a censorstation.Yes, they made some shitty decisions in that regard, but its nothing earthshaterring.

Second, they wont and really cant touch the bigger titles, given that Atlus, and by extent Sega, are important publishers in the platform.They can do that for the smaller publishers that are also really explicitive with their content.

Poll needs an option for "won't censor Caterine, and who knows what they'll do with Persona?"

No logic explaining why they would censor Catherine (unless it actually lives up to the suggestive sub title, which I doubt), nor any logic why we should connect these two games in our minds. Is Persona way more sexy than I thought?

Most of all, though, you overestimate the importance of the censorship.  This will have very little impact on Sony sales, Nintendo and MS would have to try to exploit the situation with marketing a la 1990s Sega and Sony casting the "kiddie" image, but saying "we have the softcore pr0n and Sony doesn't" really doesn't help your brand with the majority population.  Also, the Sony brand (God of War, Gran Turismo, Uncharted, etc) doesn't "stick" to a "kiddie" accusation like the Nintendo brand (Mario, Pokemon, Zelda, Animal crossing, etc).

Could the competition push an "unsexy Sony" brand? I don't think enough gamers care. Could it push an "SJW Sony" brand? I think that would politicize Nintendo or MS too much.   The best bet if any would be a viral campaign throug small outlets like ....vgchartz.

censorstation? you sound like a xbox fanboy they seem to use terms like ponystation, gaystation, kiddystation and whatever else. and have you played the original catherine and the previous persona games there is nothing worth censoring in those games. i dont even know why they would consider censoring the new catherine and the next persona game.
