I'm hoping to do a bigger update with more content and sources over the next few days, hopefully with some more details of the story if it all works out.
Regarding the comment regarding the "lead" apparently hating Soul Reaver. It doesn't make any sense to me - the videos I posted are full of allusions to Soul Reaver, both direct and subtle:
-"I am a Soul Reaver" and accompanying dialogue
blocking out the sun.
-The water burning vampire death.
-Vampires with wings
-The spectral realm, complete with Sluagh-like creatures
-Activating a forge-like object
-A Soul-Reaver esque model sword
-References in the lore screenshots to the "wheel of life".
If a project lead really hated the original game, why on earth would any of the above be present? It's completely contradictory to the evidence.
I've noticed criticisms across the internet of the story and the game not looking enough like the previous games. My perspective:
Story and Script
I don't know the story (at least not yet), but from watching this video, neither do any of us. We've seen half an hour, with a brief flashback and a few dialogue scenes. We have very little information as to what would have happened after the point at which the video ends. The dialogue we have seen is from the lower classes of Nosgoth. In Blood Omen/Blood Omen 2, the lower classes did not speak with the sophistication of the main characters - the beautiful dialogue was almost always reserved for the more intelligent and educated protagonists/antagonists. Since we haven't met any of them in the video, I doubt that the vulgarities of the vampire hunters would have reflected all characters.
As I said, I'm hoping to have some new information regarding this at some point and post it.
Doesn't look like the previous games
The video was an alpha. People have been saying it looks nothing like the previous games. Blood Omen 1 didn't look like Blood Omen 2, which didn't look like Soul Reaver 1, which didn't look much like Defiance. There are similarities in character design throughout SR1/2/Defiance, but the environments are vastly varied with a range of influences. I don't see as much of a unifying art style across the games as others apparently do.
One thing to post that might be interesting though is this:

for the discovery)
This is a screenshot of a gothic structure from Legacy of Kain Dead Sun. Its from a portfolio website. It reminds me of the run down Sarafan Stronghold in SR2's demon future, and Vorador's Mansion in Defiance. Environmental allusions to previous games were probably going to be more apparent in later levels of Dead Sun. I'm hoping for more videos in the future, which hopefully might give us a clearer look at some interior structures.
I'm just speculating. I have no idea what would have been in the final game, and everyone is entitled to their opinion. I just disagree with some of those opinions.
