Now that Iwata is gone I don't really care so much.

It's just not the same anymore.

It seems like you didn't even read what I wrote because I already addressed what you just said.

What you said makes no sense so I repeated my point.  it's common sense that a game will sell more with 2 versions rather than one because a lot of the Nintendo faithful will buy both versions. 

What I said makes absolutely perfect sense

I acknowledged that people who currently own both may only buy 1 with a unified platform but that is potentially offset by people who currently own neither buying 1 sku due to having a superior library.

As for software, lets use Mario Kart for example, MK7 on 3DS has sold over 12 million and MK8 has sold over 7 million for a total of close to 20 million. Lets say MK9 on NX sells 15 million, yes that's a drop from MK7+8 but that's only one game compared to 2, its also 15 million people they can sell DLC to compared to 7 million (MK7 doesn't have DLC) and they can now release a new IP instead of working on another MK. A new IP in a new genre helps to diversify the library and potentially attract new customers.

And again you are ingoring that alot of games would see increased sales by having both audiences to sell to. Many Wii U games would see large gains by having the 3DS audience to sell to. Like I said, Splatoon/Mario Maker will sell 5 million or so, that could be 10 million if they weren't stuck on a device with a low install base, same goes for other games as well.

Alright guys, let's keep this clean and try to stay on topic, right?

OP: I'm looking forward to seeing their results/performance. In any case, it sounds like they will profit, which is always good.

Everything he said makes perfect sense.

You can be more specific imo. Sony actually had to sell several HQs worlwide and the Sony Center in Germany just a few years ago. Closed hundreds of Sony retail shops, had to sell or at least consider selling entire divisions. As long as Nintendo puts modest profits I think there is no danger to have to rely on the kinds of desperate business moves Sony had to rely to just a few years ago.

About the major losses occured by SCE until 2010, just consider that at the same time they had a profitable PSP business, we probably can´t even imagine what a money pit PS3 actually was in reality.

But here comes the catch. The dedicated handheld market will have decreased by a lot when the NX releases this year. IOS / android hadn't taken over but it has now. Sales just won't be as big. That's why I don't expect their past profits to return. The market has declined so much.

Agreed. 

Here is DS vs 3DS. And just keep in mind that you had healthy PSP sales last gen as well (which did better than 3DS) where as this gen you've just had 3DS performing the best with PSV dead. 

For that matter it´s unlikely anyone else in the dedicated videogame market will reach such heights either. DS and Wii individually have been more successful than something like PS4 in a similar timeframe. To do well you don´t exactly need to perform record sales. But I see no one make the silly claim that Sonys videogame business is performing badly despite generating far less profits in comparison.

As long as they deem the performance decently profitable enough, there´ll be continued support and new products in the same vein. If not you get news like today, with PStv getting killed off in Japan and PSV likely sharing the same fate in anot too distant future and the probability to be a dead end when it comes to future handhelds by them.

Basically the difference is future products vs the danger of no products.
