I don't even know why people are putting stock into that rumor, if it was even one to begin with. It always sounded like a thought one delirious Souls fan came with and everyone ran with. It feels like an unlikely collaboration to me, especially after the success From enjoyed by releasing a more recognizable style of game on HD consoles. Why risk it and waste time, if you ask me.
Either way, from the released material (which I'm digging), I'm not picking up on any From aesthetics. Unless they're from their pre-Souls games.
