Looking at the progress, it seems like they can build abt 1.5 storeys per mth. Hence, we may be looking at the 19th floor in Nov-Dec 09 for 487? If 488 & 490 is already completed beforehand, not sure if contractor can devote more manpower to complete 487 & speed up the progress further? Anyway, just speculating that 487ers may be getting keys in Mar 09.
