Sony is the safest choice I think when it comes to keeping the game as it is.

Kojima Prod. or Valve would have interesting takes on the game.

I honestly wouldn't want anyone to touch Uncharted after Naughty Dog is finished with it, but if it was to be continued I'd be fine with Sony Bend.

However, I really hope Sony puts Uncharted to rest.

bro polygon is only good at clickbait articles

Naughty Dog have 300 people working for them, they could afford to put a team on the next Uncharted, while they develop a sequel to The Last of Us or make another new IP.

Guerrilla Games has around 270 people, the last statement I read from them stated that they had 150 people working on Horizon, while Cambridge have said that 70 people are making RIGS.
Hell From Software has fewer staff than Guerrilla and they developed Bloodborne alongside Dark Souls 3.

London could potentially spare the resources if they're not making some big AAA projects internally, I'm pretty sure they had over 300 people working there, though they haven't announced anything big since they went silent on Eight Days and The Getaway.
Santa Monica are known to be working on a new God of War, plus they help out on smaller projects, may potentially have other new AAA projects in the works, so I don't know if they could spare staff for Uncharted.

TBH I think the best bet for Sony would be to source new staff for a new AAA studio to work on classic franchises like Uncharted, though it would require a lot of incubation time and some very skilled, experienced people, under guidance by key ND people to make it work.
Maybe Amy Hennig could return to Sony after she's finished working on the Visceral Star Wars project and then helm a studio dedicated to Uncharted, but it would depend on what happened between her, Sony and Naughty Dog.

I thought they just said they'd be happy if someone continued it as long as they were true to the series.

"A Thief's End director Neil Druckmann has now said he'd be happy for another studio to take over, but only if they were able to nail the "essence" of Uncharted."

A portal Uncharted Crossover would be interesting or l4D, I'd love to see Nick and Drake one line each other.

I think they should let the IP rest for the rest of this gen after this title and focus on something else.

Sony bend or crystal dynamics.

I say let it go

No-one, don't trust any other developer with Uncharted except maybe Rockstar cause they can do anything really but that's not gonna happen. Santa Monica is a good choice but i'd rather let them make their own games.

Btw it's Polyphony Digital, not Polygon :D
