And another thing or two...
Look at this rezoning item from an April Planning commission meeting:

Since the Austin City Centre rendering is from February I would say Huston Heights is the new name if that was being used in April through June.
Also, the Planning Commission item as well as the December and June emerging project list all have JH West 12 St Partners as the owner with no mention of the Legends developers that the Austin City Centre article says are the developers.
