I feel like "From The Beyond" isn't something From would throw out without a reveal trailer. They usually seem to go with "Project:<word related to game>", or have with the Soulsborne games, anyway. Also, "The" is capitalised, which is a very minor note, but I don't think From ever does that. (E.g Artorias of the Abyss, Crown of the ___ King, Into the Light etc.) Also, FromSoftware making a game called From The Beyond seems a bit cheesy.

All in all, I wouldn't be surprised if From has a project related to this, but I would equally not be surprised if they didn't. I guess only time will tell.
