Hope they've improved some of the boss encounters and some of the stats like how armor works (not by a lot, but balancing it a bit more). I'm actually far less afraid of some gameplay tweaks. Like how they limited grass, that's a good change.
However, the big sin is lighting. Some of the areas look utterly mundane compared to Demon's Souls (PS3), a lot due to the lighting.
Just look at the video and compare to Mind Flayers on PS3:
Visibility of VoD also seems to have increased, which in my opinion sort of ruins the disorienting nature and oppressive feel of the stage.
Have they increased the lighting just for the videos or? All in all, it feels a bit soulless compared to Demon's Souls (PS3). It looks great and will probably be an addition that those who loved DS3 will be happy with, but it just feels less scary and oppressive than Demon's Souls (PS3). Most of what Demon's Souls is known for is its levels and their moods. Boss-wise, they've been rather easy, which is why I always thought Bluepoint should stay as true as possible to the original arts-wise, but improve on the gameplay elements.
