In answer to the question as to when the updated list will be available for download, it is already. The posting from HKBWS refers to it as the 'non-rare species report form', which is rather confusing I know. However, if you download that, you'll see there is an updated list.
I'm not sure if there is a file for download that contains only the List. Probably not. However, the Excel file above can be amended very easily to only contain a list.
