I feel like they made the designs a lot less interesting overall. They also cut the tallest building as expected, but it was only by 9' (from 342' to 333') so they're still trying to get some height here! But overall, other than adding more housing, I don't really see why this would be preferred over the 1st iteration.
I think this is a work in progress. They didn't have nearly as many renderings as they did for the first version.
It's an improvement because there are more buildings arranged in a more urban pattern. I agree that open space should be going down not up, though.
It would help their case if they showed the Center for Life Science at the correct height which is almost 350', and slightly taller than the tallest proposed here.
What case?
