Nintendo really needs to do a better job of explaining the 32gb HD/Game Cards situation.

They didn't explain it once in the presentation and now everyone is thinking they'll be having to fit the usual amount of data into 32gb instead of little to none should they go physical with games.

That's not an unreasonable assumption, either, and people like Gamespot are using clickbaity titles to really exploit it little to know clarification (I believe a youtube video I saw was simply titled "Zelda BotW will fill 40% of Switch's Hard Drive"). Nintendo really should have seen that coming.

It will definitly be possible in a Vita sized handheld/phone hybrid or iPhone Plus/Galaxy Note sized slab phone with 7nm. The current slim already cut power almost in half going from 28nm to 14nm. Getting rid of the Blu-ray Drive and swapping the HDD for Flash will save a good amount of power. Of course adding in 4G LTE will ad some back into the mix, it won't be enough to make a big issue. 

All said and done, they can easily make a device that falls into the power envolope of current high end phones and tablets. The battery life for gaming would only be about 2 - 4 hours, but as a phone it could last the day in low power mode, with light gaming. Now days I see so many people plugged in or using USB battery packs, that I honestly don't think battery life would be to big of concern, just like I think Switch will be fine.

Sony has the tech, and the know how, it is just a matter of whether they want to grow their position in the market, or continue to shrink. As a Sony fan, and investor, I hope that they decide to kill off Xperia, and make tablets/phones around PS4, and massivly grow their userbase, and the revenue and profits from PSN.

I just don't see it needing to go that low. At 20 - 30 watts with a 4000mAH battery it would do just fine for light to mkderate gaming. It would not be tiny like the current smartphones, your looking at something at least an inch longer and twice as thick as an iPhone 7 Plus with the Handheld/Phone hybrid, and something about the size of a iPhone 7, but again twice as thick for a slab version.

For a low power mode to run basic opperations, they can easily sit in the 5 to 10 watt territory. They don't have to have all 8 CPU cores and all 18 GPU cores active all the time. This this chipset could easily be made to last more than a day for basic phone calls, web browsing, texting, music, etc., between AMD and Sony they have the tech and the know how.

I know some will say it is too big, but I where Levi 30/32 slim cut jeans, and I have no problem fitting an OG 3G PS Vita and an Xperia Z in one pocket. Phones don't need to be as small as the iPhone. With full access to all PS4 titles, and PSN services I think a large group of people would be prefectly happy with a phone the same size or ever so slightly bigger than the OG Vita.

Given Sony's situation I think they'd probably just continue to double down on things that are working marvelously for them (Playstation/VR) rather than risking a venture that bombed, especially given the sheer price range Nintendo has largely cornered down at the moment (entry cost almost nothing for 2DS, scaling up to the Switch).

Really, Pokemon and Monster Hunter have done more to maintain Nintendo's reign in the handheld market than anything. I just don't think Sony has much incentive to dabble there, especially when resources can be spent on "sure things" elsewhere.

I think nintendo has made some small mistakes with the Switch which should allow a competitor some decent acces. Price and overconfigurability are the biggest ones.

What sony needs to do is, like nintendo, focus on a in home gaming experience that can be taken portable, inside the home mainly but also on the road.

A successful type console IMHO would be something like a PSVita2 (64bit ARM SOC, maybe bigLittle quad/quad, whatever). USB-c, cartridges, memstick (SD pls!!), bluetooth.

Upgrade option would be to purchase a USB-c switch style dock cradle with dualshock4 for TV play (dock charges vita2 and multiple controllers). Also should be able to plug in a hard drive for storing your whole game library, some nice tool for keeping your fave mobile ones local on the psvita2.  1080p would be okay for this.

Controls of the psvita2/dualshock 4 should overlap for sanity (back touchscreen? nah).

One possible business model:

Someone can get into the ecosystem by purchasing the psvita2 bare.
TV "dock" with dualshock4 for nominal upgrade price.
On the go multiplayer: NES style bluetooth gumstick controllers (games need to specifically support these).

It would be cool if something like this happened. But who knows if sony would really do this?

Having had a psp for a while now...I do like the switch's ability to change out controls, mostly for when they wear out and finally break!

It could but I don't think it will

Nope, no handheld except Nintendo handheld.

This is what would appeal to me as well, but someone in the thread had mentioned that if Sony wasn't already working on a portable device and suddenly wanted to, the developement process would still take years, thus the alternative to the Switch would not be immediate.  Now if there is a project currenty in the works that would be a different story (also mentioned by somebody that leaks would of occured by now).  I think timing would be the factor of influence and success.
