I really doubt this is made by From Software, just doesn't look like their creature designs at all.
I know Shuhei Yoshida sent Allan Becker from Santa Monica studios to Japan to help rebuild Japan Studios, this might be one of his initiatives. I know they really want quicker dev cycles, I can only hope this turns out as good as Gravity Rush ended up being!
We'll find out on Thursday. It's definitely possible but for now we have nothing concrete to link the 2. No having a generic buzz word like "Soul" in the name is not a concrete link. No have having a by the books dark fantasy as interpreted by Japan art style is not a concrete link either.
