I would expect that those 6 structures include several low-rise buildings. The figure of '20 towers' for Cityplace only works if it is limited to 16 floors and up:
COMPLETED
49 HVE 2
40 HVE 1
36 HVE 3 South
36 Apex 2
34 Optima
32 Matrix 1
28 Matrix 2
28 Apex 1
26 HVE 3 North
EXCAVATION / CONSTRUCTION
49 West One (2007)
47 Montage (2009)
41 N2 (2007)
38 Luna Vista (2009)
18 Luna (2009)
16 Neo (2009)
APPROVED
62 Signature Tower (2012)
36 Block 29 Tower 1 (2011)
36 Block 26W Tower 1 (2010)
18 Block 29 Tower 2 (2011)
18 Block 26W Tower 2 (2010)
From this list, it looks to me like 'Parade' consists of the buildings on the 26W block, to be completed a year after the Montage + Neo (early 2009?) and Luna + Luna Vista (late 2009?) blocks.
The Block 29 towers would follow (I assume sales will start late this year or early next year), and finally, the Signature Tower would go into sales sometime soon after.
