I can't imagine they'd show that tiny little snippet at the VGAs and not show anything for another year. I'd be shocked if it's not at E3.
As for what it is, I think it could be Bloodborne 2 and I'd be really happy if that's the case, but I'm also on-board for anything they make at this point.
Curious to see if we'll see multiple From projects unveiled in the near future. They put out DS2, BB and DS3 in back-to-back-to-back years and we haven't heard much since. Could easily see there being a Bloodborne 2 and whatever this "Shadows Die Twice" game is.
