It doesn't say PS4 exclusive in the video but lots of Gaffers are confirming it's a PS4 exclusive. I'll change the title if other information comes to light. Regardless, it looks fantastic:

As mentioned earlier, we are currently aiming to make it a downloadable title for PS4. I can't say more than that and what's in the blog post, but it's really encouraging to see that you guys like what we've revealed today.

Today, at the Nordic Game Conference 2014, we were awarded 500.000 Danish Kroner (67.000 EUR) in development support from the Nordic Game Program for the concept of our new IP ‘Hunger’ (working title).

‘Hunger’ is a third-person 3D action adventure game with stealth and exploration elements. A nine-year old girl named Six is kidnapped from her home and taken to work in The Maw – a surreal underwater resort catering to the whims of the powerful elite. When an unexpected twist of fate offers her a chance at freedom, Six takes a journey through the bizarre and unpredictable world of The Maw, and catches a glimpse at the corrupt heart of modern happiness.

“This is not only a huge vote of confidence from the Nordic Game Program expert group,” says CEO Ola Holmdahl. “The grant enables us to explore an idea we are deeply passionate about. Hunger holds fantastic potential, and our job now is to harness that promise into a great experience.”

 

sweeet

Looks so good that I guess I'll finally forgive them for cancelling The City of Metronome.

Unless this turns into vaporware, too. Then they're gonna get it but good!

The future of Tarsier Studios lies in our own original ideas, and the first of these is a game that is very much a spiritual successor to Metronome, whilst also fashioning a unique identity of its own. It is a game called Hunger.

Looks like something I´d definitely dig. Now if they manage to get it done this year that would be perfect

That's good to hear. Between Metronome and this it's clear that their creativity is wasted on making LittlePigBlanket games.

For me, LBPVita was and still is the best of the franchise. I think they did a great job and wouldn't consider it a waste of their talents.

I've heard nothing but good things about it but haven't played it myself. It sucks that they've spent so many years making other people's games instead of their own, though.

That I can agree with. Perhaps this game is a sign of things to come.

Art style looks amazing, especially that section in the kitchen. If the platforming is half as good then the game should be a winner.
