Again it is on the list. When the polls where taken on what features were wanted, surprisingly this was not in the top range at all, other features were deemed more important. Core stability, outside terrain and maps where high on the list. character creator, construction kit, all these were wanted more then light mapping.
Takes time to implement these features and not break anything else.
