I doubt they could get the same detail personally as they could probably get a lot more detail in now than they ever could back then. We are still far away from photo realistic graphics, I think they could come close to that now if they went pre-rendered, but it would probably be a lot of work and there would be a lot of people who would not appreciate it and complain so they would not take that chance financially.I know what you mean, but I think that RE7 proved that its getting to the point now where actual 3d graphics can be as detailed as pre rendered and give that same detail, creepy look to the world. I'm hoping they put a lot of effort into adding that detail to this game, it did look like they have from the trailer.
On another note, waiting hear something on Daymare 1998. I am also looking forward to that. It is slated to be released Q3 this year, hopefully we will see some information about it yet at E3.
