I'm thinking that it will not be a Live! venue. Those seem to be a full out commercial space.

I feel that since you have the Columbia Street 'experience' when walking from the west towards the stadiums between the Fox and new HQ. That this 'experience' will continue until you get to the park entrance. The 3D model shows a park in the space. Maybe they are contemplating adding a covered structure for the year round experience? This could be similar to the Via or Piazza at LCA, where you can have a secured area. Add some portable beer tubs and entertainment.
