There will be a new SkyClub in the new terminal in the post-security area. It wall be larger and will have the more modern design with a larger bar and food service areas. Entry on the Gate level and the Club 1 level up. It's also supposed to have runway views.
It's my understanding that all gates will be accessible from a central security access, which I imagine will be a zoo. Therefore, it;s a good thing that Club access will require a same day BP on DL.
I have not seen plans but the foregoing is what I've gotten from conversations with some of the DL folks I know.
