It's vague, as seems to be in vogue.
Residential, retail, commercial, educational and cultural space is the popular phrase.
Personally, I'd expect a fair whack of residential space with ground level F&B and serviced based retail.
15,000 sq m (maximum) is set aside for a future cultural building which...as usual...has no defined use at present. It's the light pink building to the left of the '1' in the picture Cul posted.
At first glance, I don't know that the shape lends itself to a theatre particularly well.
