I don't expect another all new handheld from Sony. However, would anyone else be interested in an updated model to the PSVita?

A new vita with a larger screen and updated specs that just plays Vita (and PS1/P/Now) games better than the current vita. Also a convenient (and not sold separately) Switch-like docking option that allows the system to run better while docked. Perhaps android OS instead of the vita's current OS which is just based on android.

Would you be interested in such a product?

thats even more ridiculous than making a new handheld

I would buy any Sony made handheld, I loved the PSP and PSVita and would definitely pick it up.

Just like PSTV then

i didnt even buy regular vita, no way id buy something like that either.

PSTV requires a tv. This would be a handheld with a tv-docking options (see the Nintendo Switch).

I don't see it becoming populat. The Vita is already a niche handheld as it it and, outside of gaming circles, people don't even know it exists. Instead of making a console that would divide the existing userbase and wouldn't bring as many new users to be worth it, why not go the other way around? The Vita TV was a great idea, a cheap alternative that would be worth it to those who already own PS3/4 controllers to play the few Vita games they'd be interested in. The fact Sony's Memory cards add up a lot to the price could've been avoided by this, but they didn't. After this, I don't think they are going to touch gaming handhelds for a while, much less Vita hardware.

Leave handhelds to Nintendo and tablet/phone makers. It's just not worth it. Sony shouldn't divert its attention away from the home console.

I know, I have both.

When I said "just like the PSTV", I meant an enhanced version of the Vita/PSTV combo

I'm interested in it in roughly the same way that I'm interested in winning the lottery.
