the decline is real

Interesting stuff, Mobiles/tablets have definitely had an impact, 3DS will be luck to topple PSP.

I wonder what the European and Japanese charts of this would look?

If Sony does not attempt another handheld, and continues with Xperia, they have no future in mobile. Handhelds are mobile, handhelds are phones, handhelds are productivity devices. Where in the world does this idea come from that handhelds and consoles can never grow, but every other kind of device can change with the times. 

Why is it that Apple could make a Handheld form factor iPhone and that would be great, but if Sony or Nintendo made a Phone version of the Vita or 3DS it would be stupid, or that is not what the devices are ment for?

It blows me away that on a gaming website their would be so much backlash at the idea of gaming companies growing their devices, and tapping a broader market. Seriously, do gamers really want Apple and Google to be the only option for home and mobile? Is the future we want one where games are looked at as rubish, and only their for the filth. 

Everybody really needs to wake up from this Android and iOS coma, and see that we have not reach the pinicle of technology. 

Handhelds are not dieing, the decline is not in the number of people that want to have a quality gaming experience on the go. The decline is in the number of people willing to pay for a mobile device that can not communicate with people beyond the 4 walls of their house. The decline is in the number of people willing to carry two mobile devices. If people can get a quality gaming experince, and still do all of the little activities they do on Android and iOS, then most the 200M+ people that bought PSP and DS would choose that device. More so, you would find a whole new group of people that would have been PSP or DS buyers, but could not justify it due to the lack of mobile communication. 

No.

PSP is at under 19 million lifetime ( around 18.8m )

3DS is NOW over 15 million, is currently massive up YOY ( +40% ) and has still minimum 2 strong holidays season, and even after that the time For sell.

As you can see in the graphs, 3DS 2015 sales are only 6 months, but even with this, is above PSP lifetime.

3DS Will end at over 20 million, and if not, still, Will easy beat PSP.

nothing.

USA = Nintendo land

fuck what the people think. :D

Again, that is complete BS. You are taking what you want and are applying it to the whole market with nothing to back it up.

You're speaking of growing their devices when in actuality they would just try to enter an already extremely crowded market, with no discernable advantage that people actually care about, todays smartphones/tablets are easily able to handle current day handheld gaming and it is also quite easily possible to connect a controller to a smartphone/tablet so even input isn't a problem should you want that. But here's the funny thing: Most people don't. You say that most people that bought a DS or PSP would go with a Nintendo/Playstation-phone if it was available (which btw entirely ignores that Sony already had a failed experiment with a PS phone), but that notion is easily disproven by what is going on in the current, especially western, market.

People are not looking for "high quality gaming experiences on the go", they are looking for quick and easy games that they can pick up, enjoy for a couple minutes on the train and then be done with it. Let me give you a personal example, when I was still living with my father his girlfriend and her kids they had 7 DS's in that house and 2 PSPs. You know what all those handhelds were replaced with? Smartphones and tablets. And nobody is complaining about the lack of high quality games on those devices cause all they want are some quick and easy games they can play when they have a couple minutes to kill, when they are looking for quality gaming they are going for consoles or PCs.

Lets be real here: You want a PS phone, nothing less, nothing more.

What a decline with the 3DS.

NX (the portable anyway) needs to have something new, some type of new thing beyond just being able to to play games on the TV.

The dual-screen thing has had it's time, they need something that differentiates the product against tablets/smartphones beyond just having buttons.

What that could be I have no idea.

In 2005 for DS sales, it's just 112k for 7 months.
