Interesting !

Yeah, my solution is stupidly overpowered for what would be demanded from it.
GDDR6 and HBM 2 offer more bandwidth per watt, compared to GDDR5: they will be nice to have in laptops and similar devices.
I doubt Sony would want to include expensive tech like HBM in a portable console, assuming they have a desire to target the masses like Nintendo.

Finding a way to store PS4 games on a portable device will probably be the most challenging problem to overcome.
SSDs are obviously pretty expensive for the capacity they offer, and who would want a hand-held device with a HDD in it.
Then again who would want a portable console with:

• Active cooling, that requires the device to have an air vent.
• Roughly three hours battery life (running AAA games).
• An SoC that launched in 2015.

There is a possibility in that direction, and we will achieve smaller chip in 2019. 7 nm is super small and it will fit PS4 APU into small device like Switch. Power consumption also will be easy and small because of die size. 

PS4 portable are more like PS4 slim but with portable aspect . It doesn't need exclusives, it just play the same games but with portability. 

Nope they aren't.... unless you are just talking about another portable in general. But definitely not a PS4 portable. Just not possible yet.

And they aren't "pushing" the PS4 slim because they have probably accepted that they don't have to. Its still selling very well at its current price and they are making a lot of money off it.

I strongly doubt sony is going to make a portabl Playstation anytime soon again.

What if it planed for 2021 or 2022  after PS5 reveal.  They will just borrow Switch concept but more powerful hardware.

I'm still not totally clear on the whole active cooling thing with regards to the Switch. I mean, I guess there must be a fan in there, but I never hear in running--not in handheld mode at least, and the only time the device is warm to the touch is after extended sessions in docked mode. Also, trust me, as someone who owned a Zune, an HDD in a portable device is a much bigger inconveniece than an air vent -- or even poor battery life.

I'm also surprised that you honestly believe a handheld PS4 is physically possible(without active cooling?), especially when the current PS4 already sounds like a blowdryer when it's running.

How much would a PS4 Portable with 8 GB RAM and at least 128 GB flash memory cost in 2019?

A Smach Z Pro is offered for $800 - $900 (and will probably stay vaporware)... and its APU is far from the performance of a PS4 Slim: https://www.smachz.com/shop/

A GPD Win 2 with even less capable hardware ain't cheap either: https://www.dragonbox.de/de/781-gpd-win-2-windows-10-handhelds-4260416652439.html?search_query=gpd+win+2&results=51

Do you really think a PS4 Portable for $500 or more will fly off the shelves?

Or that Sony will heavily subsidize the handheld to keep a price of $399... so that people can play PS4 games on that expensive hardware they already have?

1 - "As if they are planning to get rid of the sku all together"
Even if this was true, it doesn't mean what you think it means. It could very well be a Super Slim.
Again, assuming they are indeed trying to get rid of the SKU.

2 - "The PS4 is as hot as ever".
Well, the day where it's not as hot had to come...
"Why decrease expectations of the PS4?"
Again, everything that goes up, will eventually come down; Also, maybe because they know that their SW won't be as strong, where, for instance, Switch's will.

3 - "Yet what the rumors also say is that the sent out Dev Kits are not all that more powerful than current gen specs."
Portables aren't more powerful - or even equal - to the home console.
Why? Because of battery life, for example.
Switch lasts about 3 hours with a game like Zelda. How long do you think a PS4 portable would last on a more capablade HW than the PS4?
Not to mention the price of the thing or even size - to incorporate a larger battery.

"I imagine that the device would be digital exclusive actually."
PSP Go failed because the gaming market wants games on their hands, and it still does.
A digital only portable would be really DOA.
The market just isn't there yet.


You are reading to much into what is (not) happening.

i think sony should have just revised the current vita like PSP Go, with more internal memory, micro sd, and multiple account, coz there are lot of great games on vita that unfortunately will never get off of that platform

No chance
