I'm not sure what to make of it. There are a number of points both for and against this being another Soulsborne title.
On the one hand, it looks very Souls/Bloodborne. It has a lone protagonist in a ruined world, surrounded by monsters and a few people who might be sane, and the general style is very reminiscent of Bloodborne. And it's hard to make a mistake that is coincidentally a riff on "Prepare to Die," especially given how silly it is.
On the other hand, you'd think FROM would be mentioned if this was their project, given how famous they are for Soulsborne. And they are not known for characters who wear high heels into combat - they prepare more grounded character design.
My bet is that it's a non-FROM title that is trying to ride the coat tails of Soulsborne's success by going for the same general tone/atmosphere and by baiting with the tagline "Prepare to Dine." Some people are saying it gives off the vibes of a 2D side scroller, which seems plausible.
EDIT: come to think of it, most of the games aping Soulsborne are 2D. Salt and Sanctuary, Dark Maus, Hyper Light Drifter, Hollow Knight...
