CDL has a lot of projects concurrently running and most likely they will be using the same pool of resources from Hyundai E&C that they used for Livia. So looking at their construction methods, size of the project, reasonable time would be Q2 2013 to get the keys. But of course...as the defects repair for Livia gets completed over time, there can be more resources for NV because Palette's builder is someone else (not Hyundai E&C) and so from that perspective, it might be indeed faster.
Usually developer's motivation to speed up project is to get $ faster so that they can mark off the project and move to the resources to reinvest in the next project. They just collected the next 5% from me.
