Dayum, nice find.
Great interview too - looks like Related has a great leader here.
I'm sure some of the graphics whizzes here can convert the panned video image (see 1:09; also repeated at 3:30) into a JPG to post here. In the interview he says it will be 57 stories tall.
But the design doesn't suggest SCB to me. Certainly could be a DeStefano (I could not find a website for whatever successor firm would be designing this) I would say. It's kinda unique, it's a bold presence on the river, but it's not earthshattering, and certainly isn't exciting without an evident cantilever.
However, the video's 500 N LSD design is out-of-date, so maybe this is not a final design.
People complaining about the lack of unity between the original base and the resumed tower will be happy with the uniform style though.
