I can also report a mega development is being planned after Urby Harborside is complete.

104 and 105 on the development map is being planned for a thousand units each. The site is larger than Urby, but for ballpark comparisons, the Urby towers are ~750 units and rising 69 floors. What will a thousand unit building bring?
Harborside Plaza 4 is now planned to be mixed use. The number of units, not including the sizeable office component is 1,500. I'm assuming it will be another twin tower development as the site is farily large and it would be impossible to have a million sqft office building plus 1500 units on top. Although, it would explain this rendering.
Harborside Plaza 4 is the really tall tower on the left.
